Question

hold a glass slab at one end with your hand and stand in sunlight see the Shadows of your hand and glass slab explain what you observed​

Answer 1

Answer:

Our shadow will black and glass reflex seven colour

Answer 2

•We will observe light rays travelling through air entering glass slab and getting refracted and bending towards the normal.

•When a ray of light enters a glass slab from air then its speed decreases as it encounters a dense medium.

• Since to conserve energy, the frequency must remain constant, the wavelength of light changes.

• Wavelength is decreased by a factor called refractive index of the medium.

• It will retrace it's path after exiting the slab.
