[J2 Physics PMCians] All that’s happening with Diffraction Grating and Single Slit
What we did in 2 hours:
This week, we made use of the basic concept of using Path Difference (which we learnt last week) to determine if waves will interact Constructively or Destructively.
By the end of the lesson, you are now familiar with
1) the 3 types of Diffraction Grating questions, and comfortably use the equation to find the position of Maxima,
2) how to use the Single Slit equation to solve various questions (emphasis: the equation is used to find the position of the 1st Minima).
In the next lesson, we will unveil the secrets behind the Single Slit equation, and end of our revision with Stationary Waves.
Till then, wishing all a blessed Chinese New Year holiday! Stay safe and healthy!
