Homework Problem 1A.9

Postby Emma Randolph 1J » Tue Oct 09, 2018 9:30 pm

When trying to determine the wavelength and energy of photon for when the wave has a frequency of 300MHz, how would you do it? I'm confused how to apply the equations to the problem.

If the wave has frequency 300Hz, you can use wavelength = speed of light/frequency to find the wavelength. To calculate energy, you can use energy = Planck's constant x frequency.

To find the wavelength you first convert the frequency of MHz to Hz. Then using the equation c=(lambda)v, you can find the wavelength.
