Question

What is the period of a wave if the wavelength is 100 m and the speed is 200 m/s?

(a) 200,000 s

(b) 2 s

(c) 0.5 s

(d) 100 s

Answer 1

Uh it's c) 0.5 :), and for some reason i need to write 20 characters to explain it well, okay you need to divide speed/wavelength, that's it

Answer 2

It's 0.5 I thought it was 2 but I was wrong it's 0.5
