a) λ= 3.27m
b)E = 3.97 × [tex]10^{-19}[/tex]J
c)E= 1.325 × [tex]10^{-17}[/tex]J
Explanation:
Write down the values given in the question,
To calculate the broadcast wavelength of radio station,
a)
λ = 3 × [tex]10^{8}[/tex] [tex]\frac{10^{8}}{91.5 × 10^{6} }[/tex]
λ= 3.27m
b)
E = hf
= h × 6 × 10^{14}
E = 3.97 × 10^{-19} J
c)
E= hc / λ
= h × 3 × 10^{8} / 15 × 10^{-9}
E= 1.325 × 10^ -17 J
