Boojho made light from a laser torch to fall on a prism. Will he be able to observe a band of seven colours? Explain with a reason.

It depends on whether it is a white light that hits the prison.

Explanation:

If the light from the laser is not white then he wont be able to see all seven colours because it is only a white light that absorbs other colours and when it hits the prism it will refract and therefore he will see all seven colours

b.transmitters send radio waves, and receivers capture radio waves.
