What is the relationship between wavelength and frequency in a mechanical wave? Question 5 options:

Directly proportional - as frequency increases, wavelength increases

Independent - frequency and wavelength do not affect each other

Inversely proportional - as frequency increases, wavelength decreases

It depends on the medium or the kind of wave

This is the substance(s) formed in a chemical reaction.

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?

The molecular mass of a gas is (select all that apply) a. independent of the type of gas b. the same number as the atomic (or molecular) mass, but measured in grams c. dependent on the temperature d. the mass of a mole of the gas
