Exploring Refraction and Reflection of Light

What caused the power outage in the video?

• A power surge

• A storm

• A short circuit

• A blown fuse

What is the main difference between a flashlight and a laser light?

• A flashlight emits white light, which is a combination of all light waves

• A laser light emits multiple colors

• A flashlight emits only one color

• A laser light is weaker than a flashlight

What does the term 'cohesion' refer to in the context of laser light?

• The bending of light through different materials

• Beams of light with the same wavelengths traveling together

• The spreading out of light as it travels

• The combination of different light waves

What is the result of light waves traveling in unison in a laser?

• A weaker beam

• A dim beam

• A scattered beam

• A strong beam

What happens to light when it passes from one transparent material to another of different density?

• It reflects

• It scatters

• It absorbs

• It refracts

What is the term for light bending as it passes through different materials?

• Reflection

• Absorption

• Diffusion

• Refraction

Why did the book not work in reflecting the laser light?

• It was too small

• It had a rough surface

• It was too light

• It was too thick

What happens to light when it hits a smooth, opaque surface?

• It diffuses

• It refracts

• It absorbs

• It reflects

Why do dark surfaces absorb more light energy than light-colored ones?

• They have a higher density

• They reflect light in all directions

• They have a rougher texture

• They absorb more wavelengths of light

What saved the day in the video?

• Reflection and absorption

• Refraction and absorption

• Diffusion and reflection

• Reflection and refraction
