Front

As you go from X-rays to visible light rays, what happens to the energy of the waves?

Back

The energy of the waves decreases.

Front

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are used in microwave ovens.

Front

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

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What type of light is emitted by the sun?

Back

The sun emits a broad spectrum of electromagnetic radiation, including visible light, ultraviolet light, and infrared radiation.

Front

What is the visible spectrum?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, ranging from red to violet.
