Light Waves Chapter 2 Flashcard

Front

What is the wavelength of light?

Back

The wavelength of light is the distance between successive peaks of a light wave, which determines the type of light (e.g., visible, ultraviolet).

Front

What types of light do grow bulbs emit to help plants grow?

Back

Grow bulbs emit visible and infrared light, which are essential for photosynthesis.

Front

How can you determine if a laser is emitting a different type of light?

Back

You can determine this by comparing the wavelength and amplitude of the light emitted; different wavelengths indicate different types of light.

Front

Which type of light is least likely to penetrate the Earth's atmosphere?

Back

Gamma rays are least likely to penetrate the Earth's atmosphere due to their high energy and interaction with atmospheric particles.

Front

What type of light does Australia receive more of compared to Brazil?

Back

Australia receives more ultraviolet light than Brazil.

Front

What is the difference between visible light and infrared light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye, while infrared light has longer wavelengths and is not visible.

Front

What is the role of ultraviolet light in the environment?

Back

Ultraviolet light helps in the production of vitamin D in humans and can also cause sunburn.

Front

What happens to light when it passes through a prism?

Back

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

Front

What is amplitude in the context of light waves?

Back

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

Front

How does the intensity of light relate to its amplitude?

Back

The intensity of light is directly proportional to the square of its amplitude; higher amplitude means brighter light.
