Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
Q33.1
there are 3 long wires that are parrallel to each other . all 3 carry equal currents of I=4.00A. When observed from the top view (refer to image provided for diagram), the wires are situated at the cirners of a square with all of the currents flowing upwards. please calculate the direction and magnitude of the magnetic feild at:
a). the corner that is empty
b). the very middle point of the square.
