A hypothetical electromagnetic wave is show below. A hypothetical electromagnetic wave is show below. The frequency of the wave is (x × 10^ 19 ~Hz). x = ______ (nearest
The frequency of the wave is (x \times 10^{19} \mathrm{~Hz}). x=x = ______ (nearest integer)

Correct answer

0

Step-by-step solution

λ=1.5×4pm=6×10−12 meter λv=C6×10−12×v=3×108v=5×1019Hz\begin{aligned} & \lambda=1.5 \times 4 \mathrm{pm} \\ &=6 \times 10^{-12} \text{ meter } \\ & \lambda v=\mathrm{C} \\ & 6 \times 10^{-12} \times v=3 \times 10^8 \\ & v=5 \times 10^{19} \mathrm{ Hz}\end{aligned}
