In a double-slit experiment, light from two monochromatic light sources passes through the same double slit. the light from the first light source has a wavelength of 645 nm. two different interference patterns are observed. if the 8th order bright fringe from the first light source coincides with the 9th order bright fringe from the second light source, what is the wavelength of the light coming from the second monochromatic light source?

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.

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