Answer:
v = 0.375 m/s
Explanation:
Given that,
The wavelength of a wave is 0.75 m/cycle
The period of a wave is 2s/cycle
We need to find the speed of the wave. We know that,

Substitute all the values,

So, the speed of the wave is equal to 0.375 m/s.
The correct answer would be to express large and small numbers.
Assuming all three bulbs are connected properly with their conductivity creating a circuit, if one is unscrewed all bulbs would shut off causing zero emission of light to be displaced. Meaning answer D would be the closest to the right response.
Hope this helps! :)
