If the small particles in the atmosphere can only scatter light of shorter wavelength, then why the sky is blue but not violet? Violet should have been scattered the most.
Good question. It depends on the intensity of sunlight... if you observe the graph, the intensity of component colors of white light rises gradually from Violet and is the most at Yellow... then decreases again till Red. It is a parabola (VIBGYOR) Hence, the intensity of Blue light is way more then the intensity of violet light in a ray of white light. Hope it helped.
Sir i think your fatafat series is sabse best itne Kam time mai you and your team explain all the concepts very easily and the concepts are very clear too. Thankyou so much sir for that much effort for us🙏🙏😁
Sir please next chapter heredity and evolution and sir definitely teach evolution part because syllabus might be reduced in cbse board but state board students are also learning from you only 🙏🙏
Because at 25 cm, our ciliary muscles contract a lot. So to view objects placed nearer than 25 cm, our ciliary muscles have to contract to great extent.. hence our eyes struggle to focus clearly
3:06 A small correction in the diagram here sir . We know that most amount of refraction occurs at the cornea of the eye . Therefore , in the diagram at the right side of the screen , we must show the rays being refracted at the cornea and then further refraction at the eye lens . Btw , these series are a great help for me .
