That formula includes the wavelength which is what I am trying to solve for. I am a first year physics student so you'll have to take it easy.

A question has been given to me: what is the wavelength for light with a frequency of 5.58×1014 Hz? How do you find the wavelength without the distance?

I am looking at an image of a periodic wave. Each increment on the equilibrium line is 420 cm. there are 4 increments between the end of one full wave and the beginning of the other. How do I set this problem up to find the wavelength for this wave?

Thank you Nylex, but that was the first thing I did. I am still getting a "incorrect answer". Yes, I am looking at a picture of a wave. I though I was dong something wrong so I multiplied the number of increments times the given lenght. Am I wrong or am I missing a step?

I have a picture of a wave I am looking at. Each increment on the equilibrium line is 420 cm. I am asked to find the wavelength. there are 7 increments between one location of the first wave and the second wave. I multiply 7 times 4.2 meters and the answer is still wrong. Why?

ok, thanks

This is Anastasia's height. I'm trying to find Joe's...

Period = 1/Hz

The problem is I get 2.96E-4 when I multiply 675*5 then divide 1 by that. I must be doing it wrong

:cry: Let' say you have a wave plotted out on a time scale. Each increment on the line is 675 ms. There are 5 increments between each wavelength. How would I find the frequency so that I can solve for the wave's period using: Period = 1/Hz

I figured this out, thanks.

If I decrease vf, will I deliver greater impulse?

A 77.0 kg rider sitting on a 6.6 kg bike is riding along at 8.1 m/s in the positive direction. The rider drags a foot on the ground and slows down to 4.0 m/s still in the positive direction. What is the change in momentum of the rider and bike?

Yes I got it. Thanks all!

A wandering tapir trots along at 9 ft/s for 9 minutes, then walks at 6 ft/s for 7 minutes, and finally runs at 27 ft/s for 1 minutes. How do I find the average speed of the tapir ? I have already added the numerators and denominators then divided by 3
