EM Waves

An electromagnetic wave , whose wave normal makes an angle of 45^(@) with the vertical , travelling in air strikes a horizontal liquid surface . While travelling through the liquid it gets deviated through 15^(@) . What is the speed of the e.m. wave in the liquid , if the speed of electromagnetic wave in air is 3xx 10^(8) m/s ?

How is electromagnetic wave produced ? Draw a sketch of a plane e.m. wave propagating along X-axis depicting the directions of the oscillating electric and magnetic fields.

The phenomenon of polarisation of electromagnetic wave proves that the electromagnetic waves are

The short wavelength electromagnetic wave emitted by nuclei are called
