Physics: Light Reflection, Refraction, and Color Worksheet

Question 1

A flashlight shines on a flat mirror. What happens to most of the light when it hits the mirror?

Accepted Answer

Most of the light reflects, or bounces off, the mirror. A smooth mirror reflects light in a clear, organized way, which helps form an image.

Question 2

Explain the difference between reflection and refraction in your own words.

Accepted Answer

Reflection happens when light bounces off a surface. Refraction happens when light bends as it moves from one material into another, such as from air into water.

Question 3

A straw in a glass of water looks bent or broken at the water line. What causes this effect?

Accepted Answer

The straw looks bent because light refracts when it travels from water into air. The change in direction makes the straw appear to be in a different place.

Question 4

A student sees their face clearly in a shiny spoon but not in a rough rock. Why does the spoon make a clearer reflection?

Accepted Answer

The shiny spoon has a smoother surface, so it reflects light more evenly. The rough rock scatters light in many directions, so it does not make a clear image.

Question 5

White light passes through a prism and spreads into red, orange, yellow, green, blue, indigo, and violet. What does this show about white light?

Accepted Answer

This shows that white light is made of many colors. The prism bends each color by a different amount, so the colors spread out into a rainbow pattern.

Question 6

A red apple looks red in white light. Explain why we see the apple as red.

Accepted Answer

We see the apple as red because it reflects red light into our eyes and absorbs many other colors of light.

Question 7

A black shirt feels warmer than a white shirt on a sunny day. Why might this happen?

Accepted Answer

A black shirt absorbs more light energy from the Sun, which can turn into heat. A white shirt reflects more light, so it usually stays cooler.

Question 8

Draw or describe what happens when a beam of light hits a mirror at an angle. Use the words incoming ray and reflected ray.

Accepted Answer

The incoming ray travels toward the mirror, and the reflected ray bounces away from the mirror. The reflected ray leaves at the same angle that the incoming ray hit the mirror.

Question 9

A pencil is placed in an empty clear cup. Then water is added, and the pencil looks shifted. Is this an example of reflection or refraction? Explain.

Accepted Answer

This is an example of refraction. Light bends when it moves between water, the cup, and air, making the pencil look shifted.

Question 10

Why can you see your reflection better in calm water than in wavy water?

Accepted Answer

Calm water has a smoother surface, so it reflects light more evenly and makes a clearer image. Wavy water reflects light in many directions, which makes the reflection look broken or blurry.

Question 11

A blue marker looks blue under normal white classroom light. What color of light does the marker mostly reflect?

Accepted Answer

The marker mostly reflects blue light. It absorbs many other colors, so blue light reaches our eyes.

Question 12

Put these materials in order from most likely to reflect a clear image to least likely: mirror, notebook paper, aluminum foil, carpet. Explain your order.

Accepted Answer

A good order is mirror, aluminum foil, notebook paper, carpet. The mirror is smoothest and reflects the clearest image, while the carpet is very rough and scatters light the most.

Question 13

A rainbow can appear after rain when sunlight passes through tiny water drops in the air. Which two light behaviors help make a rainbow?

Accepted Answer

Refraction and reflection help make a rainbow. Light bends as it enters and leaves water drops, and some light reflects inside the drops before the colors spread out.

Question 14

A student shines red light on a white wall and then shines blue light on the same wall. What colors will the wall appear, and why?

Accepted Answer

The wall will appear red under red light and blue under blue light. A white wall reflects many colors, so it reflects the color of light shining on it.

Question 15

You are designing a safety vest for walking at night. Explain why bright colors and shiny reflective strips help drivers see the vest.

Accepted Answer

Bright colors are easier to see in daylight because they reflect more light. Shiny reflective strips help at night because they reflect car headlights back toward drivers, making the vest stand out.
