Answer to Question #309360 in Optics for Chemistry

Question

For a certain sinusoidal wave of intensity I, the amplitude of the magnetic field is B. What

would be the amplitude (in terms of B) in a similar wave of twice the intensity?

Answer 1

$B\sim I^2,$

$\frac{B_1}B=\frac{(2I)^2}{I^2},$

$B_1=4B.$
