Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its wavelength, frequency, and amplitude.

Front

What does wavelength measure?

Back

Wavelength measures the distance between successive crests (or troughs) of a wave.

Front

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.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the energy of the wave.

Front

What is the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from red (longest wavelength) to violet (shortest wavelength).

Front

What color of light has the highest energy?

Back

Violet light has the highest energy in the visible spectrum.

Front

What color of light has the lowest energy?

Back

Red light has the lowest energy in the visible spectrum.

Front

What is absorption in terms of light waves?

Back

Absorption is the process by which a material takes in light energy, converting it to heat.

Front

What is reflection in terms of light waves?

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, changing speed.
