2.3 Electromagnetic Spectrum Flashcard

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma rays.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases. This means that longer wavelengths correspond to lower frequencies.

Front

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

Back

Higher frequency electromagnetic waves have more energy than lower frequency waves.

Front

What type of electromagnetic radiation has the highest energy?

Back

Gamma rays have the highest energy in the electromagnetic spectrum.

Front

What type of electromagnetic radiation has the lowest energy?

Back

Radio waves have the lowest energy in the electromagnetic spectrum.

Front

What is ultraviolet radiation?

Back

Ultraviolet (UV) radiation is a type of electromagnetic radiation with a wavelength shorter than visible light but longer than x-rays.

Front

What is the effect of ultraviolet rays on human skin?

Back

Ultraviolet rays can cause sunburn and increase the risk of skin cancer due to their high energy.

Front

Define direct relationship in terms of variables.

Back

A direct relationship occurs when two variables increase or decrease together.

Front

Define inverse relationship in terms of variables.

Back

An inverse relationship occurs when one variable increases while the other decreases.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from wavelengths of about 400 to 700 nanometers.
