What happens to the frequency of a wave if its energy increases?
2 answers:
Answer: The frequency of a wave will increase.
Explanation:
The relation between the energy and the frequency is as follows;
Here, h is the planck's constant and is the frequency of the wave.
The energy of the wave is directly proportional to the frequency of the wave. The frequency is inversely proportional to the wavelength. If the energy of the wave increases then the wavelength of the wave decreases.
If the energy of the wave increases then the frequency of the wave will increase.

D. distance = 23 m, displacement = + 1 m
Explanation:
Let's remind the difference between distance and displacement:
- distance is a scalar, and is the total length covered by an object, counting all the movements in any direction
- displacement is a vector connecting the starting point and the final point of a motion, so its magnitude is given by the length of this vector, and its direction is given by the direction of this vector.
In this case, the distance covered by Karen is given by the sum of all its movements:
The displacement instead is given by the difference between the final point (1.0 m in front of the starting line) and the starting point (the starting line, 0 m):
