A circular planar wire loop is dipped in a soap solution and after taking it out, held with its plane vertical in air. Assuming thickness of film at the top very small, as sunlight falls on the soap film, & observer receive reflected light.

A

the top portion appears dark while th efirst colour to be observed as one moves down is red.

B

the top portion appears violet while the first colour to be observed as one moves down is indigo.

C

the top portion appears dark whilt the first colour to be observed as one move down is violet.

D

the top portion appears dark while the first colour to be observed as one move down depends on the refractive index of the soap solution.

A wire forming a loop is dipped into soap solution and taken out so that a film of soap solution is formed. A loop of 6.28 cm long thread is gently put on the film and the film is pricked with a needle inside the loop. The thread loop takes the shape of a circle. Find the tension in the thread. Surface tension of soap solution =0.030Nm^-1 .

A rectangular wire frame of size 2 cm xx 2 cm, is dipped in a soap solution and taken out. A soap film is formed, it the size of the film is changed to 3 cm x 3 cm, Calculate the work done in the process. The surface tension of soap film is 3 xx 10^(-2) N/m.

A U-shaped wire is dipped in a soap solution, and removed. A thin soap film formed between the wire and a light slider supports a weight of 1.5xx10^(-2)N (which includes the small weigh of the slider). The length of the slider is 30cm. What is the surface tension of the film?

Consider a U-shaped frame with a sliding wire of length l and mass 'm' on its arm. It is dipped in a soap solution, taken out and placed in vertical position as shown in figure. Choose minimum value of m so that does not descent (Surface tension of soap solution is S)

A thread is tied slightly loose to a wire frame as in figure and the frame is dipped into a soap solution and taken out . The frame is comletely covered with the film. When the portion A puntured with a pin The thread.

A thin film having refractive index mu" = 1.5" has air on both sides. It is illuminated by white light falling normally on it. Analysis of the reflected light shows that the wavelengths 450 nm and 540 nm are the only missing wavelengths in the visible portion of the spectrum. Assume that visible range is 400 nm to 780 nm. (a) Find thickness of the film. (b) Which wavelengths are brightest in the interference pattern of the reflected light?
