Waves Lesson 3 Flashcard

Front

A wave transfers...?

Back

energy only

Front

Which wave has the most energy? Options: top wave, bottom wave

Back

top wave

Front

Which wave is transferring the greatest amount of energy? Options: A, B, C, All waves are transferring the same amount of energy.

Back

C

Front

Energy is equal to amplitude squared (A²). If I double the amplitude squared (A²), what happens to the energy? Use these numbers to help you: A² = 4, E = ? A² = 8, E = ?

Back

It is doubled

Front

The drawing shows two waves. Which statement best compares these two waves?

Back

Wave 2 has more energy because it has a higher amplitude than wave 1.

Front

Which sound wave would carry more energy? Options: a wave with an amplitude of 0, a wave with an amplitude of 1.0, a wave with an amplitude of 0.5, a wave with an amplitude of 2.0

Back

a wave with an amplitude of 2.0

Front

Increasing the amplitude means you are increasing the _______________ of a wave. frequency, speed, energy, wavelength

Back

energy

Front

Wave A has a long wavelength and less frequent waves. Wave B has a short wavelength and more frequent waves. Which wave is transferring more energy?

Back

Wave B

Front

What does energy have to do with wavelength and frequency?

Back

The shorter the wavelength the more energy the wave has.

Front

If you wanted the energy of a wave to increase, you could...

Back

increase the frequency of the wave
