Question

calculate the wavelength of a electromagnetic wave whose frequency is 500×10⁶ Hz and speed is 3×10⁸m/s in vacuum

Answer 1

Dear Student

$$\begin{gathered} letthevelocityoftheelectromageneticwavev=3.0\times {10}^{8}m/s \\ Frequencyoftheelectromagneticwaveisf=500\times {10}^{6}Hz \\ lettherelationbetweenthevelocityandfrequency \\ v=f\times \lambda \\ where\lambda isthewavelengthofelectromagneticwave \\ then \\ \lambda =\frac{v}{f}=\frac{3.0\times {10}^8}{500\times {10}^6}=\frac{3.0\times {10}^8}{5.0\times {10}^8}=0.6meter \end{gathered}$$
