Answer:
0.573 m
Explanation:
From the question, It is important to note that Microwave is an electromagnetic wave and all electromagntic waves moves with thesame speed of 3.0×10⁸ m/s.
Using,
E = hv/λ....................................................... Equation 1
Where E = Energy of the radiation, h = planck's constant, v = velocity of radiation, λ = wave lenght.
Make λ the subject of the equation
λ = hv/E.......................... Equation 2
Given: E = 3.47E-28 kJ = 3.47E-25 J, v = 3E8 m/s, h = 6.63E-34 m²kg/s
Substitute into equation 2
λ = (6.63E-34×3E8 )/3.47E-25
λ = 0.573 m
Hence the wave length of microwave radiation is 0.573 m
