What happens to a car's paint when exposed to sunlight for a long time?

Back

The paint can absorb energy from the light, which can lead to damage over time.

Front

What is wavelength in the context of light waves?

Back

Wavelength is the distance between successive peaks of a wave, determining the color of the light.

Front

What is amplitude in the context of light waves?

Back

Amplitude refers to the height of the wave, which is related to the brightness of the light.

Front

How does wavelength affect frequency?

Back

When wavelength decreases, frequency increases.

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another.

Front

What is the role of light in seeing objects?

Back

Light must be reflected off an object and into our eyes for us to see it.

Front

What is the difference between a laser and other light sources?

Back

Lasers emit light that is coherent, monochromatic, and directional, while other sources may emit light of various wavelengths and directions.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light.
