Depends on the model.

The Arctic Circle and Antarctic Circle are named based on their positions relative to the poles. Arctic Circle: The word "Arctic" comes from the Greek word "arktikos," meaning "near the Bear" (referring to the constellation Ursa Major, also known as the Great Bear, which is visible in the northern hemisphere). The Arctic Circle is located at approximately 66.5° north latitude and marks the boundary where, for at least one day each year, the sun does not set (during summer) or rise (during winter). Antarctic Circle: "Antarctic" means "opposite to the Arctic." It lies around 66.5° south latitude and marks a similar boundary around the South Pole. Like the Arctic Circle, the Antarctic Circle is the region where, for at least one day each year, there is continuous daylight in summer and continuous darkness in winter. Thus, the names are derived from the Greek word for "bear" for the northern region, while the southern region is simply named for being the opposite.

@@sasthra3159 Other comments on the video seems promising...

@@sasthra3159 First time i am hearing about celestial sphere, seems nice...

Yes. It's a beautiful place in Kerala. Especially for trekking, and for those who love nature.

Pardon me. I'm unaware of the travelling telescope.

Conviced aayi.

Carbon dating typically has an error margin of about ±50 to ±100 years for recent samples, but this can increase to several hundred years for older samples due to factors like contamination and fluctuations in atmospheric carbon levels. Calibration with other dating methods helps reduce these errors and improve accuracy.

Time dilation isn't just proven by GPS. We've seen it in experiments like the muons reaching the Earth's surface and atomic clocks flown around the world showing different times. Even particle accelerators confirm it by showing longer lifetimes for fast-moving particles. Relativity is real!

@@sasthra3159 Thank you miss..

Grating glasses can't replace convex lenses as primary elements in large telescopes because they disperse light rather than focusing it, reducing light collection efficiency and image quality. Convex lenses or mirrors are better for sharp, high-resolution images in telescopes.

@@sasthra3159 Ok miss. Thank you.

Will try. Currently not interested in Electronics. Next targets are Complex Systems and ANN.

@@sasthra3159 Okay miss.

Energy is neither gained nor lost. Just redistributed between the sites of constructive and destructive interferences.

@@sasthra3159 Ok miss. But if i have two wave forms with same frequency, wavelength but 180degree phase difference. There will only be destructive interference no? Then we cannot see the bright fringes. SO in that case, where will the energy go?

@@sasthra3159 Thank you miss.

I will try. I think a prominent physicist published a paper regarding the seating problem this week.

Okay miss. Will check.

Yes, sonar can be used to detect objects inside soil, but ground-penetrating radar (GPR) is more commonly used for this purpose, as it effectively sends and receives high-frequency radio waves to identify subsurface structures. Traditional sonar is less effective in soil due to the absorption and scattering of sound waves.

@@sasthra3159 Ok miss. Thanks for the clarification.

@@sasthra3159 Miss, do post more videos about Physics.
