The back wall of a home aquarium is a mirror that is a distance of 40.0 away from the front wall. The walls of the tank are negligibly thin. A fish, swimming midway between the front and back walls,...

Light is incident from air onto the surface of a liquid. The angle of incidence is 53.0 degrees, and the angle of refraction is 34.0 degrees. At what angle of incidence would the reflected light be...

The problem says: An object is placed 25 cm in front of a convex mirror with a radius of curvature of 15 cm. The height of the object is 4 cm. Draw a ray diagram and find the location and...

A 10 µC charge is at the origin. A -5 µC charge is on the x-axis 10 cm to the right of the origin. At what point other than at infinity can a 1 µC charge be placed so that there will be no net electrostatic...
