Light - Reflection and Refraction

What is reflection in terms of light?

• Reflection is when light bounces off a surface.

• Reflection is when light passes through a medium.

• Reflection is when light is absorbed by a surface.

• Reflection is when light is scattered in different directions.

What is the effect of light traveling through different mediums?

• Light travels at the same speed in all mediums.

• Light changes speed and direction, which can cause refraction.

• Light is absorbed completely by some mediums.

• Light creates sound waves when passing through mediums.

What is the difference between reflection and refraction?

• Reflection is the bending of light as it passes from one medium to another, while refraction is the bouncing of light off a surface.

• Reflection is the bouncing of light off a surface, while refraction is the bending of light as it passes from one medium to another.

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

• Reflection is the absorption of light by a surface, while refraction is the scattering of light.

How do sunglasses work to protect your eyes?

• They increase the brightness of light to enhance vision.

• They reflect and absorb certain wavelengths of light to reduce glare.

• They block all light from entering the eyes.

• They change the color of the light that reaches the eyes.

What is the role of prisms in light behavior?

• Prisms absorb light, preventing it from passing through.

• Prisms reflect light, bouncing it back in the same direction.

• Prisms refract light, separating it into its component colors.

• Prisms emit light, producing a spectrum of colors.

What is the term for the bending of light?

• Refraction

• Reflection

• Diffraction

• Absorption

What happens to light when it hits a tinted window?

• All light passes through without any change.

• Some light is absorbed, increasing brightness.

• Some light is reflected, reducing glare and brightness.

• No light is affected at all.

What happens to light when it passes through a hand lens?

• The light is absorbed, making the image darker.

• The light is refracted, which makes the image appear larger.

• The light is reflected, causing a distortion in the image.

• The light is scattered, resulting in a blurry image.

What is an example of refraction in everyday life?

• A straw appearing bent when placed in a glass of water.

• A rainbow forming after a rain shower.

• The sound of a bell ringing from a distance.

• A shadow cast by an object in sunlight.

What is the difference between a convex lens and a concave lens?

• A convex lens diverges light rays, while a concave lens converges them.

• A convex lens converges light rays, while a concave lens diverges them.

• Both lenses converge light rays.

• Both lenses diverge light rays.
