Answer: energy of infrared radiation=13.75×10^-20J
Energy of ultraviolet radiation=8.5×10^-19J
Energy of xrays=3.7×10^-17J
Explanation:
Energy of radiation= h×c/wavelength
h=6.6×10^-34 Js
c=3×10^8 ms-1
For infrared= 6.6×10-34×3×10^8/1.44×10^-6=13.75×10^-20J
For ultraviolet= 6.6×10^-34 × 3×10^8/233×10^-9=8.5×10^-19J
For xrays= 6.6×10^-34×3×10^-8/5.34×10-9=3.7×10^-17J
