The correct answer is:
<span>B) orange, yellow, green, blue
the energy of the photons of light is directly proportional to the frequency of the light. This means that the lower the frequency, the lower the energy, and the higher the frequency, the greater the energy.
Therefore, the order in increasing energy is exactly the same as the order in increasing frequency, which is:

orange, yellow, green, blue </span>
In a string of length L, the wavelength of the n-th harmonic of the standing wave produced in the string is given by:
The length of the string in this problem is L=3.5 m, therefore the wavelength of the 1st harmonic of the standing wave is:
The wavelength of the 2nd harmonic is:
The wavelength of the 4th harmonic is:
It is not possible to find any integer n such that , therefore the correct options are A, B and D.
