The resultant amplitude in interference with two coherent sources depends upon :-

Phenomenon of interference is observed:-

A uniform rope having some mass hinges vertically from a rigid support. A transverse wave pulse is produced at the lower end. The speed $\left(v\right)$ of the wave pulse varies with height $\left(h\right)$ from the lower end as:-

A plane wave $y=a\sin (bx+ct)$ is incident on a surface. Equation of the reflected wave is $y^{\text{'}}=a^{\text{'}}\sin (\mathrm{ct}-bx)$. Which of the following statements is not correct?

A string is cut into three parts, having fundamental frequencies ${\mathrm{n}}_1,{\mathrm{n}}_2$ and ${\mathrm{n}}_3$ respectively. Then original fundamental frequency $\text{'}\mathrm{n}\text{'}$ related by the expression as (other quantities are identical):-

An object of specific gravity $\rho$ is hung from a thin steel wire. The fundamental frequency for transverse standing waves in the wire is $300 Hz$. The object is immersed in water, so that one half of its volume is submerged. The new fundamental frequency (in $Hz$ ) is:-

The frequency from $3\times {10}^9 \mathrm{Hz}$ to $3\times {10}^{10} \mathrm{Hz}$ is
