AQA Chapter 14 Light

What does the law of reflection state?

• A) Angle of incidence equals twice angle of reflection

• B) Angle of incidence equals angle of reflection

• C) Angle of incidence is less than angle of reflection

• D) Angle of incidence is greater than angle of reflection

In a plane mirror, the image formed is:

• Real, inverted, same size as object

• Virtual, upright, laterally inverted

• Real, diminished, upright

• Virtual, inverted, magnified

What is meant by specular reflection?

• A) Scattering of light by a rough surface

• B) Reflection in a single direction without scattering

• C) Scattering of sound by a smooth surface

• D) Refraction through a transparent surface

When light passes from air into glass, it:

• Slows down and bends towards the normal

• Speeds up and bends away from the normal

• Slows down and bends away from the normal

• No change in speed

Which wavelength of visible light is refracted most by a glass prism?

• Red

• Blue

• Green

• Violet

What type of image is formed by a plane mirror?

• Real and inverted

• Virtual and upright

• Real and upright

• Virtual and inverted

What is the main difference between transparent and translucent objects?

• Both let all light pass straight through

• Transparent objects scatter light, translucent transmit without scattering

• Transparent objects transmit light without scattering; translucent scatter light within

• Both absorb all light

What happens when white light passes through a red filter?

• Only blue light passes through

• All colors pass through

• Only red light is transmitted; other colors are absorbed

• No light passes through

What does magnification produced by a lens compare?

• Image size with object distance

• Image height with object height

• Lens focal length with thickness

• Object height with lens aperture

Which lens is used for correcting short sight (myopia)?

• Convex lens

• Concave lens

• Plano-convex lens

• Bifocal lens
