Wave energy & Doppler Shift/Effect

What is the doppler effect?

• a change in the frequency of sound, light or other waves to cause a change in pitch

• A change in pitch that causes frequency, sound, light and other waves to disappear

• I have no idea

• A change in sound that alters frequency

What can the Doppler effect be experienced with?

• Water

• Any type of wave

• Sound, Pitch, and Frequency

• Frequency

when a noise is moving towards an observer, the closer it comes...

• the lower the pitch

• the longer the noise

• the higher the pitch

• the quieter the noise

the doppler effect causes a shift in...

• pitch

• wavelength

• frequency

• All of the above

when the frequency is higher what happens to the wavelength?

• the wavelength gets longer

• The wavelength gets shorter

• the wavelength doesn't change

• I have no idea

• Objects move towards us, give off blue light

• Objects move towards us, give off red light

• Objects move away us, give off blue light
