Can a converging lens be made to diverge light if placed in liquid? How about a converging mirror?

A virtual image is often described as an image through which light rays don't actually travel, as they do for a real image. Can a virtual image be photographed?

Explain why a mirror cannot give rise to chromatic aberration.

a vertical pencil of rays comes from bottom of a tank filled with a liquid.when the tank is accelerated with an acceleration of 7.5m/s^2,the ray is seen to be totally reflected by liquid surface.what is minimum possible refractive index of liquid?

For light of wavelength 589 nm, calculate the critical angles for the following substances when surrounded by air: a. fused quartz b. polystyrene, and c. sodium chloride

A ray of light is incident on the surface of a block of clear ice at an angle of 40.0 degrees with the normal. Part of the light is reflected, and part is refracted. Find the angle between the reflected and refracted light.

Two opaque cups have a coin in the bottom of each. One is filled with water and the other is empty. When the two cups, side by side are viewed from an angle so that you can see half of the coin in the water cup, the coin in air is not visible. Explain this.

Explain why a diamond loses most of its sparkle when submerged in carbon disulfide.

When light (or other electromagnetic radiation) travels across a given region a. what is it that oscillates? b. what is it that is transported?
