Base your answer to this question on the information below and on your knowledge of physics. A wave traveling through a uniform medium has an amplitude of 0.20 meter, a wavelength of 0.40 meter, and a frequency of 10 hertz.
Determine the period of this wave.

What’s the period of this wave ?

T=1/f

= 1/10

= 0.1 s

v = wavelength × frequency

= 0.40m × 10 Hz

= 4ms^-1

T = wavelength / velocity

= 0.04m / 4 ms^-1

= 0.1 m

Explanation:

so first i used the formula T=1/f and i found that the period, T is 0.1s

and secondly , to check whether i got the correct answer , i used a different formula

i used the formula T = wavelength / velocity

but there's an unknown in it , that's the velocity

so to find the velocity , i used the formula v = wavelength × frequency

when i've done the calculation , the second value of T is same as the first value of T

so , the value of the period, T is 0.1s

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

i think the answer is a, hope this : )
