I would say that B seems more accurate because rhythm and tone seems like a poem
Answer:
There are basically seven spectral types which are used for classifying the stars and it is arranged in the order of increasing temperature from the hottest temperature to the coldest division are: O, B, A, F, G, K, and M. These categories are basically divided into the sub category in the spectral where O is the hottest type and M is the coldest type.
Sound at air in STP travels at 343 m/s.
We also know the formula v=f lambda where v is the velocity, f is the frequency and lambda is the wavelength.
Substituting in values to this, we get:
343 = 256 * lambda
lambda = 343/256
=1.34 3sf
Aaand upon doing this, I realise your textbook wants you to assume the speed of sound to be 330m/s, right then, well changing the value to 330, we get 1.29m
