Question

Which sets of data show a wave with the shortest wavelength?
speed = 100 million m/s and frequency = 50 million Hz
speed = 150 million m/s and frequency = 1500 Hz
speed = 300 million m/s and frequency = 100 Hz

Answer 1

I think it's c but im not a hundred percent sure

Answer 2

Thank you

Answer 3

Your Welcome :)
You Fan though :P

Answer 4

You can find the answer using the basic wave equation: v=fλ, where v is the speed, f is the frequency, and λ is the wavelength.

In this case we're trying to solve for wavelength, so just rearrange the equation: λ=v/f.

For A we have (10^8)/(5*10^7) = 2 m
For B we have (1.5*10^8)/(1.5*10^3) = 10^5 m
For C we have (3*10^8)/(10^2)=3*10^6 m

You can see from this simple calculation that A has the shortest wavelength, so that's your answer.
