A wave traveling at a speed of 0.09 meters per second has a frequency of 3Hz. What is its wavelength? (Formula: wavespeed = wavelength x frequency)

0.01m
0.03m
0.09m
0.27m

The correct option is (b) i.e. 0.03 m.

Explanation:

We have,

Speed of a wave is 0.09 m/s and the frequency of a wave is 3 Hz.

It is required to find the wavelength of a wave.

The speed of a wave in terms of wavelength and frequency is given by :

So, the wavelength of a wave is 0.03 m.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
