What characterises Electro-magnetic radiation 1. Wavelength 2. amplitude - height of wave from centreline to peak 3. Polarization - orientation vector of photons 4. frequency - number of wave cycles Why can people get sunburnt whilst sitting in the shade 1. Reflected UV radiation 2. Scattered UV radiation - from atmosphere and clouds What is a high pass filter? - Image enhancement technique which enhaces the edges and finer details of an image - This is done by subtracting a lo...

unpolarized light will have electric components and magnetic components that are pointing in all directions. The electric field and direction of travel of light must always be perpendicular. The electric field of an electromagnetic wave is what determines the polarization the wave It is not possible for the axis of polarization of light, and the direction of travel of said light, to be parallel. All objects are going to emit some amount of light, called thermal radiation, because they ...
