Answer:

All electromagnetic waves move at the speed of light (3 x 108 m/s).  Thus, for any electromagnetic wave:

Step-by-step explanation:

c = νλ

Thus, the wavelength, λ, is:

λ = c

λ = (3 x 108 m/s)/(8 x 1014 Hz)  *Note: Hz =

λ = 3.75 x 10-7 m

but wavelength of an electromagnetic wave is usually given in nanometers, so:

λ = 3.75 x 10-7 m x (1 nm/(1 x 10-9 m)

λ = 375 nm

Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field.

Frequency and wave length

All electromagnetic waves move at the speed of light i.e 3 x 108 m/s.  Thus, for any electromagnetic wave:

formula:

c = νλ

wavelength = c/λ

Thus, the wavelength, λ, is:

λ = (3 x 10^8 m/s)/(8 x 10^14 Hz)  

λ = 3.75 x 10-7 m

λ = 3.75 x 10-7 m x 10-9 m)

λ = 375 nm answer
