SC.7.P.10.1 WAVES

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Waves with long wavelengths have low frequencies, and waves with short wavelengths have high frequencies.

Front

What is a diffraction grating used for in optics?

Back

A diffraction grating is used to separate white light into various colors of the visible spectrum.

Front

What part of the electromagnetic spectrum can humans see?

Back

Humans can see the visible light part of the electromagnetic spectrum.

Front

What does a wave carry?

Back

A wave carries energy.

Front

How is the light spectrum utilized in astronomy?

Back

The light spectrum is used in astronomy to analyze the composition, temperature, density, and motion of celestial objects.

Front

What are the main types of electromagnetic waves?

Back

The main types of electromagnetic waves include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

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 visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from about 400 nm (violet) to 700 nm (red).

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual wave displacements.
