Key Insights

• 🆎 The maximum order of diffraction in a grating can be calculated using the formula n = (a + B) / λ, where a and B are distances in the grating and λ is the wavelength.
• 🪈 The maximum order is observable when the angle of diffraction is 90 degrees.
• 🍹 The grating element, denoted as D, is equal to the sum of distances a and B.
• 🥳 The maximum order can be calculated using the ratio of the grating element to the wavelength.

Questions & Answers
