Objective: SWBAT identify how waves properties, wavelength and amplitude, impact the type and intensity of waves.

PS4-1: Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

A solar-powered toy moves when you shine a flashlight on it. Select all of the statements below that accurately explain how this happened.

Light from the flashlight carried energy.

Energy from the flashlight was absorbed by the toy.

The flashlight absorbed energy from the toy.

0

What type of energy best identifies light energy? (PE/KE/No Energy)
(Think: Does energy from light move or is it startionary?)

Practice:

Click the simulation [HERE], and enter the first simulation: Sound
Select Graph, Play Tone, and Waves from the menu options in the top right
Press the ‘green’ button to begin listening to sound
Record your observations in the table below

0

What visual changes do you notice to the graph as frequency increases?

As frequency increases, the waves become closer together and there are more of them.

As frequency increases, the waves become farther apart and there are fewer of them.

0

What visual changes do you notice to the graph as frequency decreases?

As frequency decreases, the waves become closer together and there are more of them.

As frequency decreases, the waves become farther apart and there are fewer of them.

As fequency decreases, the waves becomes shorter

0

What visual changes do you notice to the graph as amplitude increases?
(THINK: Is the graph getting taller? Shorter? Are there more/less waves?

0

What visual changes do you notice to the graph as amplitude decreases?

As amplitude decreases, the waves becomes shorter and not as tall

As amplitude decreases, the waves becomes taller

As amplitude decreases, the waves become farther apart and there are fewer of them.
