An instrument plays a frequency of 266 Hz. Another identical instrument plays a frequency of 400 Hz. How does the wavelength of each of these sound waves compare? Multiple choice question.

A)
The wavelength of 266 Hz is more than wavelength of 400 Hz.

B)
The wavelength of 266 Hz is less than wavelength of 400 Hz.

C)
The wavelength of 266 Hz is same as wavelength of 400 Hz.

D)
There is no relation between wavelength and frequency.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

idk what is it? is this a question that you know the answer or u dont
