The uncertainty principle: the photons making up the beam have to have some spread (uncertainty) in their transverse momentum because they’re confined in position to a certain beam width.
Diffraction: by creating a beam of a certain width, you must have a certain amount of diffraction that causes the beam to diverge.
Fundamentally, these are the same. They come from the wave nature of light.

What is the focal length of a concave lens?
Concave lens always produces virtual image and convex lens always produces real image.
A. True
B. FalseFocal length of the plano-convex lens is when its radius of curvature of the surface isR and n is the refractive index of the lens.
A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?

The house is losing heat to the outside air through the walls and windows at a rate of 40 MJ/J, while energy generated within the house from the people, lights and appliances amount to 6000kJ/h. For a COP of 2.4, find the power input to the heat pump
