Answer:
[tex]f=216s^{-1}=216Hz[/tex]
Explanation:
Hello.
In this case, the relationship between wavelength, speed of light and frequency is:
[tex]\lambda=\frac{c }{f}[/tex]
It means that solving for the frequency, we obtain:
[tex]f=c*\lambda[/tex]
Thus, for the given 720-nm wavelength and the speed of light, the frequency is:
[tex]f=3.00x10^8\frac{m}{s}*720.0nm*\frac{1x10^{-9}m}{1nm}\\ \\f=216s^{-1}=216Hz[/tex]
Best regards.
The frequency in hertz of the electromagnetic radiation is [tex]4.12 \times 10^{14}[/tex] Hertz.
Given the following data:
Conversion:
1 nanometer = [tex]1 \times 10^{-9}[/tex] meter
720 nanometer = [tex]7.2 \times 10^{-7}[/tex] meter
To find the frequency in hertz of the electromagnetic radiation:
Mathematically, the frequency of an electromagnetic radiation is given by the formula:
[tex]Frequency = \frac{speed}{wavelength}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Frequency = \frac{3.00 \times 10^8}{7.2 \times 10^{-7}}[/tex]
Frequency = [tex]4.12 \times 10^{14}[/tex] Hertz
