Establish the relationship between speed of sound, its wavelength and frequency. If velocity of sound in air is 340 m s–1, calculate
Derivation of formula v = ν λ. (i) 340 = 256 λ λ = 1.33 m. (ii) 340 = ν (0.85) ...

You are given kerosene, turpentine oil and water. In which of these does the light ray travel fastest? Given refractive index of kerosene = 1.44
Speed of light in a medium is inversely proportional to refractive index of the medium, i.e, v∝1/n. As refractive index of water is minimum, so light travels fastest in water.

The bulk modulus and tbe density of water are greater than those of air. With this much of information, we can say that velocity of sound in air
(d) cannot be compared with its value in water. EXPLANATION: The velocity of sound in a fluid is given as V =√(B/ρ) where B is the bulk modulus and ρ is the...
