Let's consider tunneling of an electron outside of a potential well. The formula for the transmission coefficient is Te-2L, where L is the width of the barrier and C is a term that includes the particle energy and barrier height. For a particular situation, if C 1.0 nm-1, and you find the tunneling coefficient is T-0.010 (1 % of the electron tunnels through the barrier), then what is the width of the barrier L? e-2CL, where Select the correct answer 1 of 3 attempts used

a.1.0 nm
b. 1.2 nm
c. 2.3 pm
d. 4.6 nm
e. 2.3 nm

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?
