MCQ

The figure below shows pressure variation in two different sound waves in air with time at a given position. Both the figures are drawn to the same scale. Which of the following statements is true?

A
Wave $1$ has lower frequency and smaller amplitude compared to wave $2$
B
Wave $1$ has higher frequency and greater amplitude compared to wave $2$
C
Wave $1$ has shorter wavelength and greater amplitude compared to wave $2$
✓
Wave $1$ has shorter wavelength and smaller amplitude compared to wave $2$

✓

Answer

Correct option: D.

Wave $1$ has shorter wavelength and smaller amplitude compared to wave $2$

d
(d)

As,

Amplitude $\propto$ Maximum pressure and Wavelength $\propto$ Time duration for $1$ complete variation

So, wave $1$ has shorter wavelength and smaller amplitude compared to wave $2 .$

Two straight metallic strips each of thickness $t$ and length $\ell$ are rivetted together. Their coefficients of linear expansions are $\alpha_1$ and $\alpha_2$. If they are heated through temperature $\Delta T$, the bimetallic strip will bend to form an arc of radius

A thin uniform rod of length $L$ and certain mass is kept on a frictionless horizontal table with a massless string of length $L$ fixed to one end (top view is shown in the figure). The other end of the string is pivoted to a point $O$. If a horizontal impulse $P$ is imparted to the rod at a distance $x=L / n$ from the mid-point of the rod (see figure), then the rod and string revolve together around the point $O$, with the rod remaining aligned with the string. In such a case, the value of $n$ is. . . . . .
