Q1 . Light of wavelength 540 nm is diffracted by a grating ruled with 1000 lines/cm. There are a total of 2000 lines in the grating. Find the angular deviation of the third order image.
Q 2. What is the maximum order which could be observed from the grating and light source in (2)? Choose the closest.
Megan's mass is 27 kg. She climbs the 4.8 m ladder of a slide and reaches a velocity of 3.6 m/s at the bottom of the slide. How much work was completed by friction on Megan? Imagine that air resistance is negligible.
