Answer:
O.8A
Explanation:
B) As the frequency of the wave fluctuates, its energy decreases.
C) As the frequency of the wave increases, its energy also increases.
D) As the frequency of the wave changes, its energy remains constant.
As the frequency of the wave increases, its energy also increases. The correct option is C.
The frequency of an electromagnetic wave is defined as the number of oscillations or cycles per unit of time.
The frequency of the wave, on the other hand, is directly proportional to energy.
The energy of an electromagneticwave is precisely proportional to its frequency, according to the equation E = hf, where E represents energy, h is Planck's constant, and f is the frequency of the wave.
Simply said, higher frequency waves have more energy than lower frequency waves.
This is true over the whole electromagneticspectrum, from radio waves to gamma rays. The energy carried by the wave rises as the frequency of the wave increases.
Thus, the correct option is C.

mechanical waves?
(1) Both types of waves travel at the same speed.
(2) Both types of waves require a material medium
for propagation.
(3) Both types of waves propagate in a vacuum.
(4) Both types of waves transfer energy.
Answer: The correct answer is (4).
Explanation:
Electromagnetic wave is the transverse wave. It is produced by the moving charged particle. It travels at the speed of the light. It does not require a medium to travel. It can travel through the vacuum.
In mechanical wave, there is an oscillation of matter. It requires a medium to travel.It cannot travel through vacuum. The three types of mechanical waves are longitudinal wave, transverse wave and surface wave.
The common characteristics to all electromagnetic waves and mechanical waves are both can move through matter and both can occur as a result of a disturbance. This disturbance is a result of wave transfer energy.
Therefore, the common characteristic to all electromagnetic and mechanical waves is both types of waves transfer energy.

Answer and Explanation:
In classical physics we study about macroscopic objects and in modern physics we study about microscopic objects but under some circumstances classical physics is a approximation to modern physics such as
Answer:
Classical physics is a good approximation to modern physics under these certain circumstances: Matter must be moving at speeds less than about 1% of the speed of light, the objects dealt with must be large enough to be seen with a microscope, and only weak gravitational fields, such as the field generated by the Earth, can be involved.
