Answer :
Explanation:
Given parameters:-
- Frequency of EMW is - 8.2 x 10¹⁴ Hz
To find:-
- Wavelength([tex]\lambda[/tex])?
Solution:-
Here , we are provided frequency of electromagnetic wave and we have to find the wavelength of the wave. To find the wavelength we have to divide the speed of light by given frequency. therefore,
[tex]\tt\red{wavelength( \lambda)= \frac{speed(c)}{frequency(f)}}[/tex]
[tex] \rightarrow \sf \: \lambda = \frac{3 \times {10}^{8} }{8.2 \times {10}^{14} } \\ \\ \rightarrow \sf \: \lambda = \frac{3 \times {10}^{8} \times {10}^{ - 14} }{8.2} \\ \\ \rightarrow \sf \: \lambda = 0.36 \times {10}^{6} \\ \\ \rightarrow \sf \: \lambda = 36 \times {10}^{4}m[/tex]
