What kind of reflection will happen if two plane mirrors are kept parallel?
What kind of reflection will happen if two plane mirrors are kept parallel? When two plane mirrors are kept parallel to each other infinite number of images are produced. Multiple reflection takes place that gives rise to many images. What happens is at each reflection, the incident ray of light falling on either of mirrors […]

Does acceleration depend on mass on an incline?
Does acceleration depend on mass on an incline? As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases. It is the parallel component of the weight vector that causes the acceleration. Thus, accelerations are greater at greater angles of incline. Why is […]
