Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

Short wavelength radiation (X rays) has high photon energy and does penetrate matter, including us. As wavelength gets shorter (ultraviolet, X rays, gamma rays) the radiation gets more and more penetrating, and hence more dangerous to human flesh.

0.4 A

Explanation:

From the question,

Electric power = Voltage×current

P = VI Equation 1

Make I the subject of the equation

I = P/V Equation 2

Given: P = 96 J/s, V = 230 V.

Substitute into equation 2

I = 96/230

I = 0.4 A.

Hence the current is 0.4 A
