Q1. White light (380nm-750nm) strikes a diffraction grating (870 lines/mm) at normal incidence. What is the highest-order visible maximum that is formed?

Q2. What is the smallest width of a soap film (n=1.38) that would appear black if illuminated with 510 light? Assume there is air on both sides of the soap film.

Q3. A dog running in an open field has components of velocity = 3.4 and = -1.9 at time = 10.4. For the time interval from = 10.9 to = 24.7, the average acceleration of the dog has magnitude 0.45 and direction 25.
