What is single-slit diffraction?Show answer
A single slit of width produces a broader pattern with a wide central maximum and narrow, rapidly weakening side maxima. The dark fringes occur where:
What is q1?Show answer
Distinguish between constructive and destructive interference in terms of path difference. [2 marks]
What is q2?Show answer
Two slits separated by are illuminated by light of . Calculate the angle to the second-order maximum. [2 marks]
What is q3?Show answer
Light is plane-polarised before passing through a second polariser. (a) State Malus's law. (b) If the analyser axis is at to the polarisation direction, find the fraction of intensity transmitted.
