What is the relationship between wavelength and frequency of a wave, if its velocity is constant?
Wavelength is directly proportional to the frequency.
Wavelength is inversely proportional to the frequency.
Wavelength is directly proportional to the square of the frequency.
Wavelength is twice the frequency.
If in a resonance tube, oil of density higher than that water is used, then at the resonance, frequency would

We can easily hear the sound of an approaching train by putting your ear on the track well before you could hear its sound in the air. Why?
Air is less dense to propagate sound
Sound travels faster in gases than solids
Sound travels faster in solids than gases
None of these
Boojho saw a cracker burst at night at a distance from his house. He heard the sound of the cracker a little later after seeing the cracker burst. Give reason for the delay in hearing the sound.

The main reason why we have two ears is:
to determine the direction from which sound is coming
to improve the quality of sound
to serve as a backup if one ear is damaged
to increase pitch of sound
Could you please tell me why the speed of sound is more in hydrogen than in the air we breathe? It was written in my textbook that the speed of sound is much greater in hydrogen than in air. (Hydrogen: 1270m/s & Air: 330 m/s).

wavelength
velocity
