# we learnt that the angle of incidence=to the angle of reflection..my question is that sir when we form the ray diagram of a concave mirror ie when the object is at focus then won't the angle of incidence and the angle of reflection be different?

When the object is located at the focal point, there is no location in space at which an observer can sight from which all the reflected rays appear to be diverging. An image is not formed when the object is located at the focal point of a concave mirror.
Angle of incidence is same as angle of reflection

# If light is a electromagnetic wave and light has very less mass and gravitational force is directly proportional to mass of the body and therefore this neglible mass of the sun's electromagnetic wave (light) allows them to escape the gravity of the sun and travel towards the earth .Then why this theory is not applicable or hold true for dark holes we know due dark holes's strong gravitational force light can't escape but you told gravitational pull is directly proportional to mass and light has neglible mass so it should also escape dark holes? please explain this.
