PRACTICE / Malus law

An analyzer transmits a projection

Linearly polarized light of intensity 80 W/m² meets an ideal analyzer whose axis is 60° from the polarization direction.

Find the transmitted intensity.

Organize the givens & assumptions
  • Iin = 80 W/m²
  • θ = 60°

Incident light is already linearly polarized; ideal analyzer; angle is between its transmission axis and the electric polarization.
