Electromagnetic radiation behaves both as particles (called photons) and as wave

Question

Electromagnetic radiation behaves both as particles (called photons) and as waves Wavelength (lambda)j and frequency (nu) are related according to the equation c = lambda Times nu where c is the speed of light (3.00 Times 10^8 m/s). The energy (E in joules) contained in one quantum of electromagnetic radiation is described by the equation E = h Times nu where h it Planck's constant (6.626 Times 10^-34 J s) Note that frequency has units of inverse seconds (s^-1), which are more commonly expressed as hertz (Hz). A microwave oven operates at 2 70 GHz What is the wavelength of the radiation produced by thus appliance? Express the wavelength numerically In nanomoters

Explanation / Answer

v = 2.6 GHz --> giga stands for 10^9 so 2.6*10^9

find WL

the ratio

WL = c/v

Wl = (3*10^8)/(2.6*10^9)

WL = 0.115384 m
