Radiation with frequency of a 1.85 MHz, falls in the radio wave region. What is the wavelength (in nm) of the electromagnetic radio?

λ  =  1.62×10¹¹ nm

Explanation:

Wavelength of radiation = ?

Frequency of radiation  = 1.85 MHz (1.85 ×10⁶ Hz)

Solution:

Formula:

Speed of radiation = frequency × wavelength

c = speed of wave = 3×10⁸ m/s

by putting values,

3×10⁸ m/s  = 1.85 ×10⁶ Hz ×  λ

λ  =  3×10⁸ m/s   / 1.85 ×10⁶ s⁻¹

λ  =  1.62×10² m

In nm:

1 m = 10⁺⁹ nm

λ  =  1.62×10¹¹ nm

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
