True
CD's use the principles of thin film interference and polarization
True
Decreasing the wavelength of the sources causes nodal lines in a two-point source interference pattern to move closer together

Destructive interference occurs when the resultant waveform has a smaller amplitude then each individual wave
True
Diffraction gratings provide much brighter interference patterns since more light passes through them compared with double slits

True
The difference in path lengths from a point on a given nodal line to the two sources in a two-point source interference pattern is directly proportional to the wavelength of the sources
True
