Solution

Dear Student,
$A s, w e k n o w W a v e l e n g t h (λ) = \frac{V e l o c i t y (v)}{f r e q u e n c y (f)} A s, v e l o c i t y o f u l t r a v o i l e t l i g h t i s 3 \times 10^{8} m / s N o w, λ = \frac{3 \times 10^{8}}{5.5 \times 10^{15}} = . 54 \times 10^{- 7} m = 5.4 \times 10^{- 8} m$
