Reflection, Refraction, Absorption

Front

What is absorption in the context of light waves?

Back

Absorption is the process by which a material captures light waves, converting them into energy, often resulting in an increase in temperature.

What is refraction?

Back

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

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing of light off a surface, while refraction is the bending of light as it passes through different media.

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to be completely reflected back into the medium.
