Question

I need help on finding my 1st and 2nd angles in my practice it section  aswell as my angle 3 on my exercise probem. Use image provided

PRACTICE IT
Use the worked example above to help you solve this problem. Monochromatic light from a helium-neon
laser (λ = 632.8 nm) is incident normally on a diffraction grating containing 5.55 x 10³ lines/cm. Find the
angles at which one would observe the first-order maximum, the second-order maximum, and so forth.
19.7
Your response is within 10% of the correct value. This may be due to roundoff error, or you could
have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to
minimize roundoff error.
42.3
Your response is within 10% of the correct value. This may be due to roundoff error, or you could
have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to
minimize roundoff error.
EXERCISE
HINTS: GETTING STARTED | I'M STUCK!
Suppose light with wavelength 7.80 x 10² nm is used instead and the diffraction grating has 3.43 x 10³
lines per centimeter. Find the angles of all principal maxima.
