Circuits and Light Quiz

What is refraction of light?

• Refraction is the bending of light as it passes from one medium to another, like from air to water.

• Refraction is the scattering of light in different directions.

• Refraction is the absorption of light by a medium.

• Refraction is the reflection of light off a surface.

What is the role of a lens in a camera?

• A lens focuses light to form an image, often flipping and resizing it.

• A lens captures sound waves to enhance audio quality.

• A lens filters out unwanted colors from the image.

• A lens stabilizes the camera to prevent motion blur.

What is an example of an object that refracts light?

• A glass of water

• A piece of paper

• A rock

• A metal spoon

What is reflection of light?

• Reflection is when light bounces off a surface, like a mirror.

• Reflection is when light passes through a surface without bouncing.

• Reflection is the absorption of light by a surface.

• Reflection is the scattering of light in different directions.

What is a circuit?

• A closed path through which electric current flows.

• A device that stores electrical energy.

• A type of electrical component used in circuits.

• A method of measuring electrical resistance.

What is the effect of closing a switch in a circuit?

• It prevents electric current from flowing.

• It allows electric current to flow, powering devices.

• It causes a short circuit in the circuit.

• It increases the resistance in the circuit.

What is the image produced by a camera lens?

• The image produced is usually small and upside down due to the refraction of light.

• The image produced is large and right side up due to the reflection of light.

• The image produced is blurry and distorted due to lens imperfections.

• The image produced is always in color and perfectly clear.

What is an example of light being both refracted and reflected?

• When light enters a prism and disperses into a spectrum.

• When light enters water and then reflects off the surface, it is both refracted and reflected.

• When light passes through a window and illuminates a room.

• When light hits a mirror and bounces back.

What is the difference between reflection and refraction?

• Reflection is bending as it passes through a medium, while refraction is bouncing off a surface.

• Reflection is the change in direction of a wave when it hits a surface, while refraction is the bending of waves as they pass from one medium to another.

• Reflection is bouncing off a surface, while refraction is bending as it passes through a medium.

• Reflection and refraction are the same phenomenon occurring under different conditions.

What happens to light when it strikes a surface at an angle?

• It is absorbed by the surface.

• It can be reflected or refracted, depending on the surface and angle.

• It creates a shadow behind the surface.

• It changes color based on the angle.
