But to create a two-slit interference pattern it must pass through both slits at once, so it has to be in two places. It must be a wave, and be everywhere.
Feynman resolved the paradox. Light is a particle and is in exactly one place at a time. But it has a probability function that travels like a wave, that decides the probability that the photon is in each place.
So a photon is a particle that appears in every possible way to travel exactly like a wave, except when it interacts with matter and acts like a particle.

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
