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

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 a noise if moving away from an observer...

• the pitch is lower

• the pitch is higher

• the noise is smoother

• the energy is lower

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

When pitch is lower what is happening to the frequency?

• the pitch crescendos

• It is unchanged

• None of these

• It is also lower

What is Redshift

• Objects move away us, give off red light

• Objects move towards us, give off blue light

• Objects move towards us, give off red light

• Objects move away us, give off blue light

What is Blueshift

• Objects move away us, give off red light

• Objects move towards us give off blue light

Blueshift frequency

• Is increasing

• Stays the same

• Blueshift has no frequency

• decreases
