Light Video Refraction, Reflection, Colors

What happens when light hits a smooth, shiny surface?

• It reflects at the same angle it arrived.

• It changes color.

• It gets absorbed completely.

• It scatters in many directions.

What is the angle of incidence?

• The angle at which light hits a surface.

• The angle at which light is absorbed by a surface.

• The angle at which light leaves a surface.

• The angle at which light is completely scattered.

How can you avoid unwanted reflections when taking photos?

• By moving the camera to a different angle.

• By using a darker lens filter.

• By waiting for the light source to move.

• By painting the surface matte.

How can the angle of reflection help in photography?

• By determining where to position the camera to avoid glare.

• By avoiding unwanted shadows.

• By creating a mirror effect.

• By preventing lens flare.

Why do some surfaces not create mirror-like reflections?

• Because they are not in direct light.

• Because they have a rough texture.

• Because they absorb all the light.

• Because they are too dark.

Why do we only see certain colors on objects?

• Because the object emits those colors.

• Because the object reflects those colors.

• Because the light source only provides those colors.

• Because the object is moving at a high speed.

What does it mean when light is absorbed by a surface?

• The surface reflects all the light.

• The surface changes the light's direction.

• The surface takes in the light, not reflecting it.

• The surface bends the light waves.

What effect does a rough surface have on light?

• It causes the light to bend.

• It reflects the light in one direction.

• It diffuses the light in many directions.

• It absorbs all the light.

What causes light to bend?

• Moving from one medium to another.

• Passing through a vacuum.

• Reflecting off a curved surface.

• Changing its color.

What is refraction?

• The absorption of light by a surface.

• The reflection of light at the same angle it arrives.

• The scattering of light in many directions.

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