What does the Greek letter ν (nu) represent in physics?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Frequency of a wave.
In physics, the Greek letter ν (nu) is commonly used to represent frequency. Frequency is the number of cycles or oscillations of a wave per unit time, usually measured in hertz (Hz), where 1 Hz = 1 cycle per second. For example, in wave mechanics, optics, and quantum physics, ν is used in formulas such as:
E = hν
Here, E is the energy of a photon, h is Planck’s constant, and ν is the frequency of the associated electromagnetic wave.
