Answers
Answer:
concave mirror
uses
Shaving mirrors.
Head mirrors.
Ophthalmoscope.
Astronomical telescopes.
Headlights.
Solar furnace
convex lens
A convex lens is employed in microscopes and magnifying glasses to converge all incoming light rays to a particular point. ...
The convex lens is used in cameras. ...
A convex lens is used for the correction of hyperopia. ...
The converging lens is used in the projector as well.
Shine a light through a prism, or hang one in the window on a sunny day, and you'll see a rainbow. It's the same rainbow you see in the sky because, on a day with a mixture of rain and sun, each raindrop acts as a miniature prism. For physicists debating whether light is a wave or particle, this phenomenon is a strong argument for the former. In fact, experiments with prisms were central to Issac Newton's formulation of the theory of optics and the wave nature of light.

2. A light passes through a prism ,it will bend ,or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. As a result all colours in white light of the sun separate into the individual band of colour characteristic of rainbow .
