Question

Which component of electric field amplitude \[a\] is transmitted by analyser \[P_2\]?

Options

• The component perpendicular to its pass-axis, \[a\sin\theta\]

• Neither rectangular component

• The component parallel to its pass-axis, \[a\cos\theta\]

• Both rectangular components equally

Answer 1

Resolving the amplitude relative to \[P_2\]'s pass-axis gives a parallel component \[a\cos\theta\]. The analyser transmits this parallel component.
