A) amplitude
B) frequency
C) wavelength
D) time period
Correct Answer: C
Solution :
If temperature of medium changes the velocity changes, also from \[v=n\lambda \]thus, it is also true as \[v={{\left( \frac{E}{\rho } \right)}^{1/2}}.\]Both E and \[\rho \] decrease but decrease ofE is much larges. Frequency does not change on changing the temperature, hence wave length changes.You need to login to perform this action.
