EM waves velocity

EM waves are periodic changes of electric and magnetic fields in space and time. EM waves is transverse waves. EM waves velocity. Direction of EM wave propagation. Electric and magnetic fields are produced by charges and currents, but these fields also extend into surrounding

b)Limiting angle (critical angle)

(-I-) a) medium 1 is the more refractive medium because the refracted ray deviated away from the normal . OR. b)Limiting angle (critical angle). d) = , then the incident ray is reflected. ( Total internal reflection ) .
