EM Spectrum Revoew

QuestionAnswer
What does the electromagnetic spectrum show? All types of electromagnetic waves arranged by wavelength, frequency, and energy
Which electromagnetic wave has the longest wavelength? Radio waves
Which electromagnetic wave has the least amount of energy? Radio waves
Which electromagnetic wave has the shortest wavelength? Gamma rays
Which electromagnetic wave has the most energy? Gamma rays
How are wavelength and energy related? Shorter wavelength means higher energy
How are frequency and energy related? Higher frequency means higher energy
What happens to energy as frequency increases? Energy increases
Which wave has more energy, ultraviolet or infrared? Ultraviolet
Why does ultraviolet radiation damage skin more than infrared radiation? Ultraviolet has higher energy due to shorter wavelength
Which wave has a longer wavelength, red light or violet light? Red light
Where is visible light found on the electromagnetic spectrum? Near the middle
Why is infrared placed next to visible light on the spectrum? It has slightly longer wavelengths and less energy
Which type of electromagnetic energy from the Sun reaches Earth the most? Visible light
Which waves are most likely to cause harm if exposure is too high? Gamma rays and X-rays
Why are radio waves useful for communication? They travel long distances and around obstacles
Which electromagnetic wave is used to detect heat differences? Infrared waves
Why can you feel heat from a fire even when you cannot see it? Infrared waves carry heat energy
Which property is used to organize waves on the electromagnetic spectrum? Wavelength, frequency, and energy
If one wave has a shorter wavelength than another, what can you say about its energy? It has more energy
How can you tell which wave has the longest wavelength on a graph? It appears highest or farthest on the wavelength scale
What relationship connects wavelength, frequency, and energy? As wavelength decreases, frequency and energy increase

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
