Quasars are extremely distant celestial bodies. Investigators using a special telescope determined that a certain quasar was emitting waves with a frequency of 1.41 x 109 Hz. Using the electromagnetic spectrum provided, investigators were most likely using a telescope that detects -

Scientists observed a celestial object emitting a wavelength of 3 x 10-10m. What type of telescope did the scientists have to use to view this?

In the electromagnetic spectrum, which of the following is true of waves with long wavelengths?
Sunscreen bottles often include the phrase: “Protects against UVA and UVB waves.” This refers to ultraviolet radiation coming from the sun. Which of the following is true of ultraviolet radiation?
The full range of energy in sunlight can be described as
What part of the electromagnetic spectrum can be seen by humans?
Which has a higher frequency?

The distance between E and H is called

A rainbow is sunlight disbursed into a spectrum of colors ranging from red to violet. When you are facing a rainbow, the sun is always behind you, the rain is in the direction of the rainbow, and the arc of the rainbow is directly opposite the sun. Which statement best describes the formation of a rainbow?

Our eyes detect light that lies only within a small region of the electromagnetic spectrum. This region is called visible light. Which of these statements describes the visible spectrum of light as seen by the human eye?
Electromagnetic radiation from the sun comes in all forms. Scientists have found ways to use the electromagnetic waves to study different characteristics of objects in space. Which of the following correctly pairs an electromagnetic wave with a way that it is used in space exploration?
The diagram below shows the electromagnetic spectrum. Which letters represent radio and gamma waves?

How does the hazard level of electromagnetic waves change as the frequency of the waves increases?
Meg is barbequing hamburgers on the grill. She notices that the coals are ready for cooking because she feels the warmth of the coals and sees that they are glowing red. What types of electromagnetic waves is she detecting?
Electromagnetic radiation is energy that travels in waves. Two types of electromagnetic waves are microwaves and gamma rays. Gamma rays have a shorter wavelength than microwaves. Which of these statements is true?
Astronomers often scan the sky using devices called radio telescopes. What can you conclude about these devices?

Infrared radiation can be used to take special pictures called thermographs. “Graph” means “image”. What can you infer about the prefix “thermo”?

What might happen if the ozone layer did NOT block the sun’s ultraviolet rays?

What do all forms of electromagnetic radiation have in common?
Link the following EM waves to their uses:
Group the following according to their descriptions
All EM waves travel at different speeds, depending on their energy and frequency.
Both X-rays and gamma rays have higher frequencies than ultraviolet rays.
Communicating with satellites is an application of gamma rays.
How are electromagnetic waves different from other waves?
