Microwaves, such as those used for radar and to heat food in a microwave oven, have wavelengths greater than about 3 mm. What is the frequency of radiation of wavelength 526 mm? Answer in units of s-1
microwaves are electromagnetic waves, so to calculate the frequency of the wave, we should follow this formula:
c=f*λ
being λ the wavelength and c the speed of light (equal to all electromagnetic waves)
c= 3*10^8 m/s
526mm=0.526m, then
$${\frac{\left({\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{8}}}\right)}{\left({\mathtt{0.526}}\right)}}$$ = 5.7*10^8 Hz or (s^-1)
or it could be
570 MHz
