Electromagnetic Radiation

What did William Herschel discover when he placed a thermometer beyond the red end of the visible spectrum?

• Ultraviolet light

• X-rays

• Infrared radiation

• Microwaves

Which statement accurately describes the relationship between wavelength, frequency, and energy in the electromagnetic spectrum?

• As wavelength increases, frequency and energy both increase.

• As wavelength decreases, frequency increases, and energy decreases.

• As frequency increases, wavelength decreases, and energy increases.

• As frequency decreases, wavelength decreases, and energy increases.
