Suppose you have two polarizers. The first has its transmission axis at 0 degree

Question

Suppose you have two polarizers. The first has its transmission axis at 0 degree and the second has its axis oriented at an angle theta with respect to the tint. At which of the following values of theta will the minimum amount of light be transmitted through the two polarizers? A. 360 degree. B. 0 degree C. 180 degree D. 90 degree In the polarization of light experiment, you zeroed the light senior so that all background light would be subtracted from the readings. If you had not zeroed this, what would he introduced in your data? A. Random error B. Imprecision C. Systematic error D. Wrong frequencies. Malus's law for the polarization of light is derived from the fact that an electromagnetic wave consists of an electric field vector and a magnetic field vector. The intensity of light, I, received at a point by a detector it related to the electric field, E, at that point How are the intensity and electric field related? A. I alpha cos E B. I alpha E^2 C. I alpha sin E D. I alpha 1/E To the right is a graph of the magnetic field strength inside a solenoid as a function of current. Using the information provided on the graph, what is the turn density (n) of the solenoid? The permeability of free space is mu_0 = 1.256 times 10^-3 mT times m/A A. 0.1370 m^-1 B. 16 m^-1 C. 81 m^-1 D. 109 m^-1 A current flows through a solenoid, which rests horizontally on a table with one end on your left and the other on your right. At the top of the solenoid, the current is moving toward you while at the bottom it moves away from you. Assume the current is conventional current. The direction of the magnetic field inside the solenoid is pointing A. to the left. B. to the right C. upwards D. downwards

Explanation / Answer

here,

the intensity of light transmitted , I = I0 * cos^2(theta)

for minimum intensity

cos(theta) must be 0

and so that theta must be 90 degree

the value of theta is B) 0 degree
