As a domain expert in physics, I can explain the relationship between energy and frequency. The connection between these two concepts is described by the equation of Planck-Einstein relation, which states that the energy (E) of a photon is directly proportional to its frequency (ν). The mathematical expression is:
\[ E = h \cdot \nu \]
Where \( E \) is the energy of the photon, \( h \) is the Planck's constant (approximately \( 6.626 \times 10^{-34} \) joule-seconds), and \( \nu \) is the frequency of the photon.
Now, let's address the relationship between frequency and wavelength. The speed of light (c) in a vacuum is a constant, and it is the product of the wavelength (\( \lambda \)) and the frequency (ν):
\[ c = \lambda \cdot \nu \]
Given that the speed of light is a constant (\( c \approx 3 \times 10^8 \) meters per second), if the frequency increases, the wavelength must decrease to maintain the equality, and vice versa. Therefore, higher frequencies correspond to shorter wavelengths and, according to the Planck-Einstein relation, higher energy.
So, to summarize:
- The
energy of a photon is directly proportional to its
frequency.
- The
wavelength is inversely proportional to the
frequency.
- Higher frequencies (shorter wavelengths) mean higher energy.
