BILL NYE VIDEO: WAVES
What are three things that travel in waves?
Radio Sound Light
What are three of the properties of waves?
Wavelength Frequency Amplitude
Why does light break into patterns when it is run through thin slits?
the light source split into different wavelengths, and separates the colors.
Do X-rays have higher or lower frequency than light waves? Higher
Define wavelength. The length between the top or bottom of each wave.
What causes waves on the ocean?
The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules
What are the waves in the Earth called (Earthquake waves)? Seismic Waves
Define frequency. The speed at which the wave is moving
Define amplitude. The height of the wave
What kind of wave travels by squeezing and spreading? (give an example)
Compression Waves
What is it called when a wave bounces back and comes back to the source?
Reflection
What is Sonar?
The process of sending a sound wave at a certain frequency, and timing how long it takes for the reflection to bounce off the object and get back to a sensor. This will tell you accurate distances.
