Refraction, Reflection and Absorption #1

What is absorption in terms of light?

• Absorption is the process by which an object takes in light energy, preventing it from being reflected or transmitted.

• Absorption is the reflection of light off a surface.

• Absorption is the scattering of light in different directions.

• Absorption is the transmission of light through a medium.

What is the effect of light absorption on temperature?

• Objects that absorb more light tend to get warmer because they convert light energy into heat.

• Light absorption has no effect on temperature.

• Objects that absorb light become cooler due to energy loss.

• Light absorption only affects the color of the object.

What is a common example of refraction in everyday life?

• A common example of refraction is a straw appearing bent when placed in a glass of water.

• A common example of refraction is a rainbow forming after rain.

• A common example of refraction is light passing through a prism and creating colors.

• A common example of refraction is a mirror reflecting an image.

Can you give an example of reflection?

• Seeing a mirrored image of mountains on the water is an example of reflection.

• A shadow cast by a tree on the ground.

• The way light bends when it passes through a prism.

• The sound echoing off a wall.

What is reflection?

• Reflection is the bending of light as it passes through different mediums.

• Reflection is the bouncing back of light when it hits a surface, allowing us to see mirrored images.

• Reflection is the absorption of light by a surface, preventing us from seeing through it.

• Reflection is the scattering of light in multiple directions when it hits a rough surface.

Why do we see different colors in a rainbow?

• Different colors in a rainbow are seen because each color of light is refracted by different amounts, separating them.

• Different colors in a rainbow are caused by the mixing of light and dark clouds.

• Different colors in a rainbow are a result of the temperature of the air.

• Different colors in a rainbow are due to the reflection of light off water droplets.

What is refraction?

• The process of light being absorbed by a medium.

• The bending of light as it passes from one medium to another, causing objects to appear distorted or displaced.

• The reflection of light off a surface.

• The scattering of light in different directions.

What happens to white light when it passes through a prism?

• White light is absorbed and turned into heat.

• White light is refracted and separated into its component colors (spectrum).

• White light remains unchanged and passes straight through.

• White light is reflected back without any change.

What is the principle behind seeing a rainbow?

• A rainbow is formed by the absorption of light in clouds.

• A rainbow is formed by the refraction, dispersion, and reflection of light in water droplets.

• A rainbow is created by the scattering of light in the atmosphere.

• A rainbow is caused by the interaction of light with ice crystals.

What type of surface absorbs the most light?

• Light surfaces, like a white t-shirt

• Dark surfaces, like a black t-shirt

• Reflective surfaces, like a mirror

• Translucent surfaces, like frosted glass
