Doppler

Christian Doppler explored how the motion of an object impacts the pitch of its sound.

Franz Doppler was a flutist and composer known for his superb control of pitch and tone.

They lived at the same time. 

For some reason I find this very amusing.

I wonder if they ever met.

Physics - topic 14 notes on waves. I admit that this topic is quite tricky; needs to be understood in order to attempt the past year questions. Making my own notes (with reference to given notes) actually helps a lot bc I am understanding it and writing at the same time 👍🏼 (I understand this topic better after I make my own notes) 🙌🏼

Can you explain the term redshift and any relation it may have to photons/light?

All colors of light have a corresponding wavelength, similar to sound waves. Under different circumstances, this wavelength can be stretched or squeezed, turning it into a different color. If the wavelength is stretched, it’s redshifted, and if it’s squeezed, it’s blueshifted.

You’ve probably already experienced this with sound, actually. When a car passes by, you may notice that it sounds higher-pitched when it’s coming towards you, and lower-pitched as it’s traveling away. Basically, the sound waves are getting squeezed together as the car approaches you, and getting stretched out as the car leaves. Thanks for asking!
