Help neeee part b and C only thanks A child is playing with a bubble wand, which is a large rectangular wire frame that contains a soap film. The child holds the wandvertically, which causes the film to be thinner at the top and thicker at the bottom, forming a wedge shape. Assume a thickness ofessentially zero at the top. White light shines on the film with approximately normal incidence. The child views the reflected lightfrom the film and sees the first violet interference band at a distance of 3.00 cm from the top edge of the film. The index ofrefraction of the soap film is the same as that of water, n = 1.33, and the wavelength of violet light is å = 403 nm.(a) At what distance (in cm) from the top edge of the film does the child see the first red (A = 666 nm) interference band?4.95cm(b) What is the thickness (in nm) of the soap film at the location of the first violet interference band?125.e-9Use the constructive interference condition you found in part (a) that relates the thickness to the wavelength, index ofrefraction, and integer m.
