Final answer:
The energy of light with a frequency of 12 x 10^11 Hz can be calculated using Planck's constant and the formula E = hν, resulting in 7.9512 × 10^-22 joules.
Step-by-step explanation:
To find out the energy of light with a specific frequency, we can use the formula E = hν, where 'E' is the energy, 'h' is Planck's constant, and 'ν' (nu) is the frequency of the light. Planck's constant (h) is approximately 6.626 × 10^-34 J·s.
Given a light frequency of 12 × 10^11 Hz, the energy (E) of this light can be calculated as follows:
E = hν = (6.626 × 10^-34 J·s) × (12 × 10^11 Hz) = 7.9512 × 10^-22 J
Therefore, the energy of the light with a frequency of 12 × 10^11 Hz is 7.9512 × 10^-22 joules.
