Physics: A polarized laser beam of intensity 285 W/m2 shines on an ideal polarizer. The angle between the polarization direction of the laser beam and the polarizing axis of the polarizer is 16.0 ∘. What is the intensity of the light that emerges from the polarizer?

The intensity is $I_1 = 263.35 \ W/m^2$

Explanation:

From the question we are told that

The intensity of the beam is $I = 285\ W/m^2$

The angle is $\theta = 16^o$

The intensity of the light that emerges from the polarizer is mathematically represented by Malus' law as

$I_1 = I * cos^2 (\theta )$

substituting values

I_1 = 285 * [cos(16)]^2

substituting values

I_1 = 285 * [cos(16)]^2

$I_1 = 263.35 \ W/m^2$

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
