Microsoft Edge https//session.ma temView?assignmentProblemiD-964393188offset-next January 23 Pre-Lecture Assignment Electromagnetic Radiation c) 3013 Constants I Periodic T Electromagnetic radiation behaves both as parlidles (called photons) and as waves. Wavelength (A) and trequency (u) are related according to the equation where c is the speed oflight (3.00 × 108 m/s) The energy (En described by the equation ules contained in one quantum of electromagnetic r radiation is where h is Planck's constant (6.626 x 10-MJ-s) Note that frequency expressed as hertz (Hz) has units of inverse seconds (s ), which are more commonly Part A A microwave oven operates at 2.90 GHz. What is the wavelength of the radiation produced by this appliance? Express the wavelength numerically in nanometers. View Available Hint(s) LZT Submit Part B This question will be shown after you complete previous questions)

Explanation / Answer

Given:
f = 2.90 GHz = 2.90*10^9 s-1

use:
lambda = c/f
=(3.0*10^8 m/s)/(2.90*10^9 s-1)
= 0.103 m
Answer: 0.103 m
