Explanation:
From the question we are told that
The generally equation for the mechanical wave is
The speed of the transverse wave is
The amplitude of the transverse wave is
The wavelength of the transverse wave is
At t= 0.150s , x = 1.51 m
The angular frequency of the wave is mathematically represented as
Substituting values
The propagation constant k is mathematically represented as
Substituting values
Substituting values into the equation for mechanical waves
Answer:
Frequency
Explanation:
Photons are the packet of energy. They are massless and chargeless particles. They travel in the vacuum with the speed of light. The energy of photon is given by :
Where
h = Planck's constant
= frequency of photon
Or
c = speed of light
= wavelength of photon
From the above equation, it is clear that the energy of photon is directly proportional to its frequency.
