Homework Statement:
A wave has amplitude of 6.0 cm and a frequency of 10 Hz, and the distance from a crest to the nearest trough (measured along the direction of the wave’s energy transfer) is measured to be 4.0 cm. Determine the period of such a wave.
A: 60s
B: 1.5s
C: 0.4s
D: 0.1s
E: 4s
Relevant Equations:
T (period) = 1/ frequency
I think the answer is just 1/10 (according to the formula for period), so the answer is 0.1. Is that correct?
Thanks!

That is correct. However, I am perplexed that you cannot be confident that 1/10 = 0.1.

I do not think that is the part where OP was uncertain...
