So if i take a picture (for example) 30 fps camera. So my question is that: is the time in the picture 1 s \ 30 fps or is it just 0? (May be very stupid question)
Do you know the specific formula they were using to count the distance. I am in high school and the physics course that i am having has only given me the basic equation of Waves, which is velocity = Hz x wavelength.
