Awave can be described as
a continuous transmission of energy from one location to the next.
the disturbance of particles in an area.
the transmission of energy through individual particles.
the motion of particles in a medium.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?
