The image below shows a certain type of global wind: What best describes these winds? (3 points)
a
Polar easterlies that curve due to air above poles being relatively cooler
b
Jet streams that curve due to air above equator being relatively warmer
c
Trade winds blowing in a curved manner due to the rotation of Earth
d
Polar westerlies blowing in a curved manner due to Coriolis Effect

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
