Part A:

How far away can a human eye distinguish two car headlights 1.8 m apart? Consider only diffraction effects and assume an eye pupil diameter of 5.5 mm and a wavelength of 550 nm.
Part A= L = 1.5 X 10^4 m

Part B: What is the minimum angular separation an eye could resolve when viewing two stars, considering only diffraction effects?
Part B= Theta = 0.42

Part C: In reality, it is about 1' of arc. Why is it not equal to your answer in B? <-- this part is the only one I dont know, I got the other two correct

Transformation is in fact standard lorentz transformation : Frame S' travels at speed V_1 along the x axis of frame S (in the standard configuration). Frame S'' travels at speed V_2 along the x'' axis of frame S'; (also in the standard configuration). By applying the standard Lorentz transformation twice find..

Phenomenon is called the relativity of simultaneity : A traveler in a rocket of proper length 2d sets up a coordinate system S' with its origin O' anchored at the exact middle of the rocket and the x' axis along the rocket's length. At time t' = 0 she ignites a flashbulb at O'.

Surface equals the free-fall acceleration on earth : It has been suggested that rotating cylinders about 8.0 mi long and 5.0 mi in diameter be placed in space and used as colonies. What angular speed must such a cylinder have so that the centripetal acceleration at its surface equals the free-fall acce..

Two converging lenses : Two converging lenses, one with f = 4.5cm and the other with f = 44 cm, are made into a telescope. Assume these lenses are now combined to make a microscope; if the magnification needs to be 25 X, how long would the microscope be?

How far away can a human eye distinguish : How far away can a human eye distinguish two car headlights 1.8 m apart? Consider only diffraction effects and assume an eye pupil diameter of 5.5 mm and a wavelength of 550 nm. What is the minimum angular separation an eye could resolve when view..

What is the heat gain per unit length of the duct : Airflow through a long, 0.2 m^2 air conditioning duct maintains the outer duct surface temperature at 10 C. If the horizontal duct is uninsulated and exposed to air at 35 C in the crawl space beneath a home, what is the heat gain per unit length of t..

Determine the full trajectory : Consider a positive charge q that is released from rest at the origin in the orthogonal uniform electric and magnetic fields E = E yˆ and B = B zˆ.

Oxygen molecule contains two oxygen molecules : The oxygen molecule (O2) contains two oxygen molecules, each with mass 2.7x10^-27 kg and a bond distance of 1.24x10^-10 m. Calculate the following: The moment of inertia for rotation about an axis perpendicular to the bond.

Consider an ideal monatomic gas : Consider an ideal monatomic gas of 1026 atoms. What is the internal energy of this system at 27 °C? If the temperature is raised by 1 °C, by what factor does the number of accessible states increase? What is the increase in entropy in this case?
