Verified Answer
The energy of a photon of light has what kind of proportionality to it...
As E=h(frequency) E is directly proportional to frequency and as frequency = speed of light / wavelength frequency is inversely proportional to wavelength.

The energy of a photon of light has what kind of proportionality to it...
Explanation:
The energy of a photon of light is given by the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. The equation can also be written as E = hc/λ, where λ is the wavelength of the photon and c is the speed of light.
Proportionality to frequency:
- As per the equation E = hf, the energy of a photon is directly proportional to its frequency.
- This means that if the frequency of a photon increases, its energy also increases, and vice versa.
- Therefore, the option 'directly' is correct for the proportionality between energy and frequency.
Proportionality to wavelength:
- As per the equation E = hc/λ, the energy of a photon is inversely proportional to its wavelength.
- This means that if the wavelength of a photon increases, its energy decreases, and vice versa.
- Therefore, the option 'inversely' is correct for the proportionality between energy and wavelength.
Conclusion:
- The energy of a photon of light has a direct proportionality to its frequency and an inverse proportionality to its wavelength.
- Hence, the correct option is 'A' (directly, inversely).
