Using the interference formula to calculate the wavelength of the laser light, λ. Show your work below. (Your answer should be really small!) Variable Equation: y=mλLd Substitute Values here: y=mλLd Solve for wavelength: y=mλLd = (yd)/((m)(L))=λ = Compare your result to the actual wavelength of the laser, which is 6.32 X 10-7 m (this would be your "accepted value" in your percent error calculation). How close is your result? (Give math answer AND then explain in a sentence) Note: the experimental value for the wavelength is your answer to #5! Variable Equation: Percent Error = accepted value - experimental valueaccepted value 100 Substitute in Values here: Percent Error = accepted value - experimental valueaccepted value 100

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
