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 'Coulomb's force vs the Lorentz force'

Beams of electrons and protons move parallel to each other in the same direction. They ______. a. attract each other. b. repel each other. c. neither attract nor repel. d. the force of attraction or repulsion depends upon the speed of the beams. This is a previous-year-question of CBSE Board 2023. The answer key marks (b) as the right option. I want to know why we are ignoring Coulomb's force?
