PhySci Light Flashcard

Front

What is the relationship between pitch and sound frequency?

Back

Pitch is directly related to the frequency of sound waves; higher frequencies correspond to higher pitches.

Front

What type of wave is a light wave classified as?

Back

A light wave is classified as a transverse wave.

Front

What are the potential dangers of high concentrations of visible light?

Back

High concentrations of visible light can cause burns, blindness, and indirect DNA damage.

Front

What determines the color of visible light?

Back

The color of visible light is determined by its wavelength.

Front

In the Bohr atomic model, where are electrons located?

Back

Electrons are located in orbits around the nucleus.

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 electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, X-rays, and gamma rays.

Front

How does light behave when it passes through a prism?

Back

When light passes through a prism, it is refracted and dispersed into its component colors, creating a spectrum.

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 is the sum of the individual waves.

Front

What is the difference between reflection and refraction of light?

Back

Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes from one medium to another.
