When two or more waves overlap, the resultant displacement at any point and at any instant is found by adding the instantaneous displacements that would be produced at the point by the individual waves if each were present alone.
truefalseTrue or False30s - Q7
Light waves are reflected from the front and back surfaces of such single slit, and constructive interference between the two reflected waves (with different path lengths) occurs in different places for different wavelengths.
falsetrueTrue or False30s - Q8
The complex shapes of the colored patterns result from variations in the thickness of the film.
truefalseTrue or False30s - Q9
You cannot observe a similar diffraction pattern by looking at a point source, such as a distant street light, through a narrow slit formed between your two thumbs held in front of your eye.
falsetrueTrue or False30s - Q10
The amplitude of the resultant wave is the sum of the amplitudes of the individual waves.
truefalseTrue or False30s - Q11

Alight with a wavelength of 700 nm is shined on two small slits. The distance between the slits is 1.5mm and the screen is placed 4m away from it. The light shines brightest at the central maximum. Find the distance from the central maximum where the first maximum will be located on constructive (bright) interference.

Alight with a wavelength of 700 nm is shined on two small slits. The distance between the slits is 1.5mm and the screen is placed 4m away from it. The light shines brightest at the central maximum. Find the distance from the central maximum where the first maximum will be located on destructive (dark) interference.
