Constructive and Destructive interference ish kinda ... mayve

Basic but very good idea of constructive and destructive interference

http://physics.info/interference/

if you set the speeds to be equal then you will see Standing interference between two waves

diffraction at a single slit

with reference to significance of

the wavelength.

Nodes on a plate

Suitable method of demonstrating the wave nature of light.

Lasers are powerful due to constant constructive interference
