1. what is the angular separation (between a grating and screen) of the second order maximums produced by 420nm and 300 nm wavelengths incident upon a 450 lines/mm diffraction grating 2. Boron nitride (a lubricant) with an index of refraction of 2.0 is heated within a microwave oven. If the speed of the microwaves is 3.0X108m/s, what is the speed of the microwaves in the boron nitride

i) Find the angular separation between the red hydrogen-α spectral line at 656 nm and the yellow sodium line at 589 nm if the two lines are observed in third order with a diffraction grating having 3 500 slits per cm. (Give the answer in degrees, correct to three significant figures.) [6] (ii) Using the same diffraction grating as in (i) , what is the highest order that could possibly be observed using violet light of wavelength 420 nm?

Is the angular momentum of a planet conserved as it orbits a star? Explain your answer using torque. Conservation of angular momentum: The angular momentum of an object or system is conserved whenever the total external torque on the object or system is zero. τ ⃗_ext=0 → ∆L ⃗=0

A copper disk at 850 degrees celsius rotating about its axis with an angular speed of 25 rad/s in the outer space. As the disk radiates infrared light, its temperature falls to 20 degrees celsius. No external torque acts on the disk. Does the angular speed of the disk change as it cools?
