A mass of 1.5 kg rests on a horizontal table and is attached to one end of a spring of spring constant 150 N mł. The other end of the spring is moved in the horizontal direction according to x = a cos omega t where a = 5 x 10-3 m and omega = 6π rad s 1. The damping constant b = 3.0 N m-'s. Determine the amplitude. Show that if the applied frequency were adjusted for resonance, the mass would oscillate with an amplitude of approximately 2.5 x 10-2 m.

But splitting of white light takes place because it is not a single wavelength but it is a combination of different wavelengths & prism can detect only the wavelengths not the colours..... 🙏🙏 As usual easiest way of explaining guru ji 👍
Electrical pulse produced due to differences of concentration of sodium or chlorine etc produce electrical pulse ,now for different colour sense wise the different voltage produced for accumulation of different number of electrons make it different colour .Light in fact no colour but in such way the difference voltage production wise different colour produced
Excellent Harish Chandra Verma sir. Sir can you help us by teaching class 12 physics . Anyway you are always doing great work. Keep it up harish sir. Keep shining like the sun and spread your light everywhere
Dispersion only happens when a polychromatic light goes from one medium to another medium because of more than 1 wavelengths which the light constitute. Because the refractive index for different wavelengths is different also in same medium, that's why white light disperses into VIBGYOR. But when a monochromatic light (means the light which constitutes of only one wavelength) goes from one medium to another medium then there will be no dispersion because the light will have waves of only one refractive index.
Bro Diamond is also same . Diamond Very Good Conductor of Heat But Very Bad conductor of Electricity. Reason For Diamond : Bad Conductor of Electricity : Because there is No Free Electron as all the valence electrons are used in sp³ hybridization covalent bonding. Now Good Conductor of Heat : Because of Vibration produced by the rigid atomic structure of the diamond thats phonone Vibration. The Heat wave is carried out and hence Diamond conducts heat. Similar reason is for the Mica.
There can be TWO CASES as the Incident light (which gives sensation of purple colour in brain) can be of TWO types- One is the emw of only one wavelength of purple colour And the other is mixture of two different emw of different wavelengths (of blue and red). This also gives sensation of purple colour in brain. When the former is passed through prism, there is NO SPLITTING. But when latter is passed through prism, it SPLITS into blue and red colours.
i got your answer...but when we mix blue and red then this time we are not mixing wavelengths, we are acctually mixing chemicals which reflect the light of any wavelength in purple color light of wavelength 390nm ...so first we cannot prepare a purple colour wavelength by just adding two chemical colours....it is just that the new formed chemical reflect a light of wavelength of purple colour which is 390nm....so on refraction through prism it will not split
@@nambi045 thanks for seeing my answer.....but I think you didn't get my point...... Let, we have two laser lights one is blue (with wavelength corresponding to blue colour) and other red (with wavelength of red)( both are monochromatic) When we mix these lights we get a mix of these lights whose beam will have em waves of both wavelengths (there will be no intermixing of wavelengths but our eye will see it as purple colour). Now when we pass it through prism it will split into its components i.e. blue and red (due to difference in wavelengths) Now if we take a laser of purple colour, it will emit emw of only one wavelength corresponding to purple colour. As it will have only one component, by passing through prism, its beam will deviate but not split... Hope you would get my point!!!🙂
@@rohit.individuals You cannot mix two laser lights. Both light rays will be different and their wavelengths will be different, wavelength of light rays will not mix thats why they will refract at different angles, but u cant say that this is dispersion. because there are two light rays which are refracting individually , and not any component of light is breaking. there are 2 light rays with 2 different wavelength and therefore refracting with different angles. thats all
@@technicalworld8113 I will be dispersion!!! If not, then you can't say that sun light undergoes dispersion as according to you, it is mix of many lights (many wavelengths) and all lights will refract individually......But this is not True. Any light which undergoes dispersion is a mix of 2 or more em waves with different frequencies and wavelengths.....
@@technicalworld8113 ek mix of light me alag alag wavelengths ka alag alag refraction hona hi toh dispersion hai!!! Yeh mix 2 light ka bhi ho sakta hai...red or blue....or brain me components individually nhi dikhta, yeh mix purple dikhega or dispersion bhi karega.... Or second case hai jisme monochromatic purple light hoga with only one wavelength...no dispersion. Yeh sir ne video me bataya hai!!!
When white light passes through a glass prism, it splits into the seven constituents of light ( VIBGYOR) so both the primary as well as secondary colours appear except cyan and magneta. Since the refractive index of different colours are different in a particular media so they deviate with different angles
White light(radiation) have a range of wavelenght which get arranged in a order when passed through a prizm and the spectrum obtained is descending order of wavelengths of white light.When this spectrum is sensed by our eyes brain categories the single into seven parts which is the colors of light. We should also remember that any color like red color light does not have that fixed wavelength always it is also a range of wavelengths.
In th Electromagnetic Spectrum, in the visible range, you can't see white color anywhere, nor you have read if white colour has a fixed wavelength This is because we can see white color when all the 7 colours of visible range come together
@@shivanshujaiswara @divya is correct , bcoz there is always Heisenberg uncertainty principle. You cannot tell precise value of wavelength.... There is always spread ( may be very small )....
Ji sir questions Q1 why electron don't move first gain energy goes n 1 to m 3 then absorb then absorb more energy in the excited state and reaches further in upper shell ? Q2 neon ka aur sodium +1ka spectrum same hoga ?
prism split the light . so we can say light is a mixture of different waves length that why prism split. then why not magenta colour is mixture of two different waves length. light is a energy . it also possible that two different waves length gives a resultant wave length . which is magenta colour.

which has a greater resistance a 100w bulb or a 60w bulb
sir if we use p=v^2/r we get tht 60w bulb has more resistance here we get p is indirectly propotional to r
but why dont we use p=I^2R here we get p is directly proportional to r
which formula must be used for this qs?
Because Voltage is constant normally in any supply like house 🏡 supply 250 V .
And Current is itself variable for both the cases. Hence for comparison
P=V²/R is used and not I²R .
It will depend on whether it is in series or parallel.
In our house we use parallel connection, so voltage is same. Thus use V²/R
In domestic supply voltage is constant
