The Electromagnetic Spectrum

What characteristic do all parts of the electromagnetic spectrum share? They have the same wavelength. They have the same frequency. They interact in the same way with any matter. They travel at the same speed through empty space.

Kamala made a table to describe parts of the electromagnetic spectrum. What mistake did Kamala make? Gamma rays should have a very high frequency, not a very low frequency. Visible light should have a low frequency and a long wavelength. Infrared light should have a short wavelength, not a long wavelength. Microwaves should have a high frequency and a short wavelength.

Which part of the electromagnetic spectrum is typically used to make images based on the temperatures of objects? X-rays radio waves infrared light visible light

If humans cannot see ultraviolet waves, how can ultraviolet light be used to gather evidence of a crime? Ultraviolet light detects the presence of radioactive substances. Ultraviolet light shows cold areas as blue and warm areas as red. Ultraviolet light causes substances to fluoresce and give off visible light. Ultraviolet light transmits information to AM and FM radio receivers.

Which types of electromagnetic waves have longer wavelengths than the waves that make up visible light? Check all that apply. radio waves gamma rays microwaves infrared light ultraviolet light X-rays

Which types of electromagnetic waves have higher frequencies than the waves that make up ultraviolet light? Check all that apply. radio waves infrared light microwaves gamma rays visible light X-rays

Quentin made a table to summarize uses of electromagnetic waves. Which should he write in the "Use" section for X-rays? music broadcasts luggage inspections night-vision goggles digital photographs

Someone places a chocolate bar near a working radar set that is used to locate ships and airplanes. Which best describes what is likely to happen to the chocolate bar? It changes color as it absorbs visible light from the radar set. It softens and melts as it absorbs microwaves from the radar set. It becomes radioactive after it absorbs gamma rays from the radar set. It begins to fluoresce after it absorbs ultraviolet light from the radar set.

How can electromagnetic waves be used to fight a forest fire? Gamma ray images can show hot spots as radioactive areas. Ultraviolet images can show hot spots as fluorescent areas. X-ray images can show hot spots as white areas. Infrared images can show hot spots as red areas.

The part of the electromagnetic spectrum that has the longest wavelengths is .
