The speed of sound depends on the nature of the medium. Sound travels the fastest in solids. Its speed decreases in liquids and it is the slowest in gases.
Therefore, for a given temperature, sound travels fastest in iron.
(a) At room temperature (25 °C), water is a liquid because it has the following characteristic of liquid:
(i). At room temperature, water has no shape but has a fixed volume...
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.
1. Odisha-Jharkhand Belt- Famous for Haematite iron ore. Badampahar Mines in the Mayurbhanj and Kendujhar districts. Singhbhum district of Jharkhand.
2. Durg-Bastar-Chamdarapur Belt- High Grade Haematite ore. Chhatisgarh and Maharashtra.Bailadadila range...
(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...
(c) Wavelength .
EXPLANATION:
When the sound wave is being sent by a tuning fork, its displacement amplitude, frequency and the time period will remain the same even if the temperature changes....
