Write an expression for a linearly polarized lightwave of angular frequency  and amplitude E propagating along a line in the xy-plane at 45 degree to the x-axis and having its plane of vibration corresponding to the xy plane. At t=0, y=0, and x=0 the field is zero

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
