Answer:
0.316 m
Explanation:
The wavelength of an electromagnetic radiation is given by the formula :
Speed of the electromagnetic radiation/ frequency of the electromagnetic radiation
Speed of electromagnetic radiation is given by 3*10^8 m/s
Frequency of the electromagnetic radiation is 9.50*10^8 Hz
Substituting the relevant values in the above formula:
3*10^8/9.50*10^8 = 3/9.5=0.316 m
So the required wavelength is 0.316 m
