Which is the definition of refraction? 1)the blocking of light waves vibrating in a particular plane

2) the bending of a light wave as it passes at an angle from one medium to another

3) a false or distorted image causing the gradual distortion of light through hot air

the redirection of light by tiny particles as it passes through a medium

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
