Final answer:
The frequency of the wave is unknown, but the wavelength is 2.29 x 10^30 m.
Step-by-step explanation:
The frequency of a wave can be calculated using the formula:
frequency = speed/wavelength
In this case, we are given the energy of the wave (1.31 x 10-22 J), but we need to know the speed to calculate the frequency. If we assume that the wave is an electromagnetic wave, we can use the speed of light (3.00 x 108 m/s). Assuming the wave is an electromagnetic wave:
frequency = speed/wavelength
1.31 x 10-22 J = (3.00 x 108 m/s) / wavelength
Solving for wavelength:
wavelength = (3.00 x 108 m/s) / (1.31 x 10-22 J)
wavelength = 2.29 x 1030 m
Therefore, the frequency of the wave is unknown, but the wavelength is 2.29 x 1030 m.
