Final answer:
The energy of a radio wave with a wavelength of 93.1 cm is approximately 2.137 x 10^-25 J.
Step-by-step explanation:
To find the energy of a radio wave with a wavelength of 93.1 cm, we can use the equation E = hc/λ, where E is the energy, h is Planck's constant (6.626 x 10^-34 J*s), c is the speed of light (3.0 x 10^8 m/s), and λ is the wavelength in meters. First, we need to convert the wavelength to meters: 93.1 cm = 0.931 m. Plugging the values into the equation, we get:
E = (6.626 x 10^-34 J*s)(3.0 x 10^8 m/s) / 0.931 m = 2.137 x 10^-25 J
Therefore, the energy of the radio wave with a wavelength of 93.1 cm is approximately 2.137 x 10^-25 J.
