Grade 2 Physics Quiz: Interaction of Light with Matter

What is reflection of light?

• The process where light gets absorbed by a surface.

• The process where light bounces off a surface.

• The process where light disappears into thin air.

• The process where light changes color when it hits a surface.

What are some examples of reflection of light in everyday life?

• Fire, smoke, air

• Mirrors, windows, water, shiny surfaces

• Wood, plastic, metal

• Clouds, trees, rocks

How does a mirror reflect light?

• The mirror reflects light by bouncing it off its smooth surface.

• The mirror absorbs light and then emits it back out

• The mirror creates its own light to mimic the objects in front of it

• The mirror refracts light by bending it as it passes through

What is refraction of light?

• The bending of light as it passes from one medium to another.

• The emission of light from a source

• The reflection of light off a surface

• The absorption of light by a medium

How does a straw appear bent in a glass of water?

• Scattering of light

• Refraction of light

• Absorption of light

• Reflection of light

What happens to light when it passes through a prism?

• It is refracted and separated into its component colors.

• It turns into sound

• It becomes invisible

• It disappears completely

What is dispersion of light?

• Absorption of light by an object

• Separation of light into its different colors

• Reflection of light off a surface

• Combining of light into a single color

How does a rainbow form?

• Rainbows are created by unicorns using their magic horns

• Sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere.

• Rainbows form when the sky is sad and starts crying colors

• Rainbows are painted by fairies in the sky

What are some effects of interaction of light with matter?

• Absorption, reflection, refraction, and transmission

• Refraction, scattering, absorption

• Absorption, deflection, transmission

• Reflection, absorption, emission

How does light make objects visible?

• By making objects disappear

• By creating shadows on the objects

• By making objects transparent

• By reflecting off the surface of the object and entering our eyes
