Question1
A source emits 531.62-nm and 531.81-nm light.
(a)What least number of grooves is required for a grating that resolves the two wavelengths in the first-order spectrum?
(b) Conclude the slit spacing for a grating 1.32 cm wide that has the necessary minimum number of grooves.
Question2
In outer space, far from other objects, block 1 of mass 70 kg is at position < 10, 10, 0 > m, and block 2 of mass 800 kg is at position < 22, 10, 0 > m. What is (vector) gravitational force acting on block 2 because of block 1?
Question3
