of hoice the linear dimension of the object Object
and screen are then moved unnil the image is three
Kmes the size of the object. If the shift of the screen
PS 25cm, determine the shift of the object and the
focal length of the mirror.​

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
