Explanation When the pipe is closed at one end, only odd harmonics are present, where first harmonic is the fundamental and other such as third, fifth and seventh are over tunes. As the tube is closed from both the end, it will behave same as the string attached to both end of any instrument such as open pipe, so wavelength of fundamental frequency is twice the length of the hallway acting as a closed tube. Write the expression for wavelength. λ = 2 l (I) Here, λ is the wavelength of this string and l is length of the hallway. For a closed tube expression for the frequency in relation with the wavelength is given below. Write the expression for frequency. f n = n v λ (II) Here, λ is the wavelngth of sound wave, v is speed of sound and f is the frequency. Substitute 2 l for λ in eqaution (II)

Review Conceptual Example 2 before attempting this problem. Two slits are 0.158 mm apart. A mixture of red light (wavelength = 693 nm) and yellow-green light (wavelength = 567 nm) falls on the slits. A flat observation screen is located 2.42 m away. What is the distance on the screen between the third-order red fringe and the third-order yellow-green fringe? m = 3 m = 3 m = 0 m = 3 m = 3 Fringes on observation screen

A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in visible light with wavelength 643 nm in vacuum. Assuming that the visible spectrum extends from 380 to 750 nm, what is the longest visible wavelength (in vacuum) for which the film will appear bright due to constructive interference? Number Units
