16.Two waves Y₁ and Y2 propagate in space by the following equations
Y₁=7 sin (ωt+π/3)
Y2=5 sin (ωt+π/2)
When they get interfered, the resulting wave will have new amplitude and
propagation equation, find:
a) The amplitude
b) The wave propagation equation.
17. A light source emits visible light of two wavelengths λ=430 nm and λ'= 560 nm. The
source is used in a double-slit interference experiment in which L= 1.59 m and
d=0.0240 mm. Find the separation distance between the second-order bright fringes?
18. A double-slit interference experiment is set up using a light source that emits visible
light of two wavelengths: 21 = 480 nm and 22 = 620 nm. If the distance between the
slits and the screen is L = 2.0 m and the separation distance between the slits is d =
0.030 mm, calculate the separation distance between the third-order bright fringes.
19. A light source emits light of two wavelengths: 21 = 400 nm and 22 = 550 nm. In a
double-slit interference experiment with L = 1.8 m and d = 0.020 mm, determine the
separation distance between the fourth-order bright fringes.
20. In a double-slit interference experiment, a light source emits light of two
wavelengths: 21 = 600 nm and 22 = 700 nm. If the distance between the slits and the
screen is L = 2.5 m and the separation distance between the slits is d = 0.025 mm,
find the separation distance between the fifth-order bright fringes
21. Write the intensity of light after passing through polarizer and analyzer rotating by
600?
22. Two polarizers are orientated with their axes at an angle of 30.0°, what proportion of
the original light remains?
