Wave Period Calculation: Is 0.1 the Correct Answer for Frequency of 1/10?

Click For Summary
The discussion centers on the calculation of wave period, specifically addressing whether the frequency of 1/10 corresponds to a period of 0.1. Participants confirm that the calculation is indeed correct, affirming that 1/10 equals 0.1. There is some confusion about the necessity of additional information provided in the question. Ultimately, the consensus is that the relevant data was appropriately identified. The conversation highlights the importance of clarity in understanding basic mathematical relationships in wave calculations.

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...
 
The question offers you more information than needed. You correctly chose the relevant datum.
 
Thanks everyone! I was just unsure whether I needed all the extra info or not.
 

Thread 'Bernoulli vs real life experiment'

If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
