What’s the frequency (in mega hertz) of a beam of red light whose wavelength is 6000 A

Answer 1

To find the frequency of a beam of light with a given wavelength, we can use the formula:

c = λν

where c is the speed of light, λ is the wavelength, and ν is the frequency.

The speed of light is approximately 3.0 x 10^8 meters per second.

First, let's convert the wavelength from Ångstroms (A) to meters (m):

6000 A * (1 m / 10^10 A) = 6.0 x 10^-7 m

Now, we can rearrange the formula to solve for the frequency:

ν = c / λ

ν = (3.0 x 10^8 m/s) / (6.0 x 10^-7 m)

ν = 5.0 x 10^14 Hz

Finally, converting the frequency from Hz to megahertz (MHz):

5.0 x 10^14 Hz = 5.0 x 10^11 MHz

Therefore, the frequency of a beam of red light with a wavelength of 6000 A is approximately 5.0 x 10^11 MHz.
