st. waves r formed when 2waves of same freq. in opp. direction superimpose with each other
light waves when incident perpendicularly on reflecting surface then reflected wave is 180 degree out of phase with incident wave
both when superimpose will produce stationary waves with bright antinodes &dark nodes .

When two waves of the same wavelength are 180 degrees out of phase, they will destructively interfere with eachother.
When the crest of one wave means the trough of another wave (180 degrees, 1/2 cycle, apart), they cancel out.
You are left with noting.

ya standing waves r used in light waves. reason is the total internal reflection prnciple is there. u can understand

gentle can work together with itself. gentle can behave like a wave and waves work together in a technique called interference. look at the two-slit test for information in this and its function in quantum concept.
