Red laser light from a he-ne laser (λ = 632.8 nm) creates a second-order fringe at 53.2° after passing through the grating. what is the wavelength λ of light that creates a first-order fringe at 22.0°?

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
