What is the refractive index of a medium?

the ratio of the speed of light in vacuum to the speed of light in the medium

the ratio of the speed of light in air to the speed of light in the medium

the ratio of the speed of light in the medium to the speed of light in air

the ratio of the speed of light in the medium to the speed of light in vacuum

A ray of light in a glass block is incident on a boundary with air at an angle of incidence of 40°. The critical angle at this boundary is 43°. What happens to the ray of light at the boundary?

It is partly reflected back into the glass and partly refracted into the air

It is partly reflected back into the glass and partly refracted along the boundary

It is totally reflected back into the glass

It is totally refracted into the air

The diagram shows an object O placed 3 cm away from a converging lens of focal length 6 cm. What type of image is produced?

virtual, inverted and diminished

The diagram shows a single ray of light being directed at a plane mirror. What are the angles of incidence and reflection?

angle of incidence = 50°, angle of reflection = 50°

angle of incidence = 40°, angle of reflection = 40°

angle of incidence = 40°, angle of reflection = 50°

angle of incidence = 50°, angle of reflection = 40°

A lens forms a blurred image of an object on a screen. How can the image be made sharp and in focus on the screen?

by using a lens of longer focal length at the same position

by moving the object away from the lens and screen

by moving the screen away from the lens and object

by using a brighter object at the same position

A ray of light passes from water into perspex. What is the correct explanation of the refraction?

The ray refracts towards the normal because the speed of light is less in perspex than in water.

The ray refracts away from the normal because the speed of light is greater in perspex than in water.

The ray refracts away from the normal because the speed of light is less in perspex than in water

The ray refracts towards the normal because the speed of light is greater in perspex than in water.
