Question

Describe an activity to show the speed of light is different in different media 2 for 10 class​

Answer 1

Answer:

Different photons have different energies, which also means their electric and magnetic fields oscillate at different rates. While the speed of all different types of light is the same in a vacuum, those speeds can be different in any sort of medium.

Answer 2

Answer⤵️

When a beam of white light incident on a prism, it disperse colours at different angles, known as dispersion. This beam will have a colour band, in which all the colours are arranged according to their wavelengths.

If we arrange one of prism in opposite manner, then the dispersed colours merge into white light beam again.

When white light passes through a prism, a band of seven colours is obtained, which is called the spectrum. The seven colours in the spectrum are violet, indigo, blue, green, yellow, orange and red from down to up.
