2025 Light Waves Quiz

First and Last Name

When wave energy is trapped in a medium and doesn't pass through it

• reflection
• transmission
• absorption

When wave energy strikes a new medium and passes through it

• reflection
• transmission
• absorption

When wave energy bounces off a medium causing the wave energy to change direction.

• reflection
• transmission
• absorption

The bending of light waves as they travel from one medium to another

• rarefaction
• refraction
• reflection

If you can see yourself in an object, the object is

• opaque
• non-reflective
• reflective

Which is the light wave color we can see on the visible spectrum with the longest wavelength?

• Gamma rays
• Green
• Violet
• Red

Why do we see a red apple as red?

• red light is being reflected fro the apple while the other colors are being absorbed
• red light is being absorbed while the other colors are being reflected
• all colors are being reflected, but we only see red

How do we see objects around us?

• The light from our eyes illuminates the object.
• Every object emits light toward our eyes.
• Light reflects off the object and reaches our eyes.
• Light reflects off our eyes and toward the object.

If I want to increase the brightness (intensity) of a light wave, I need to increase the

• frequency
• amplitude
• reflection
• transmission
