How does EMR differ from other waves? |
Requires nommedium for transmission Oscillates the field not the media Adsorption and emisson and radiant energy cannot be explained in terms of EMR being a wave, but more in twrms of EMR being made of particles |
|
|
|
Energy of a photon (formula) |
Frequency x h h= planks constant 6.63x10^-27 erg sec |
|
|
|
Frequency formula |
Velocity /wavelength |
|
|
|
Contance of frequency |
Frequency remains the same regardless of what media light travels through. |
|
|
|
Wave front |
A surface that connects similar points. |
|
|
|
Wave normal |
A line at right angles to the wave which represents the direction of the wave's movement. |
|
|
|
Light ray |
Direction of propagation of light energy |
|
|
|
Amplitude |
Wave height |
|
|
|
Wavelenth |
Distance between successive peaks or troughs |
|
|
|
Period |
Time taken for the passage of one complete wavelength through a fixed point |
|
|
|
Frequency (definition) |
Number of oscillations per second. |
|
|
|
What does it mean when retardation is i, i+1/2 or any other number (phases) |
i+1 =destructive interference i=constructive interference Anything else= partially constructive interference |
|
|
|
How can you derive the component of a resultant wave direction |
Draw component wave in an abritary direction Construct right anhled triangle with reaultant as hypotenuse XCostheta

|
|
Polychromatic light |
Light that consist of all wavelengths, white light |
|
|
|
Monochromatic light |
Lihtof a much narrower band of wavelengths |
