number of wavelengths/amplitude

# Which formula should she use?
distance traveled / amplitude

number of wavelengths/amplitude

number of wavelengths/time

distance traveled / time

distance travelled /time

Explanation:

because speed=distance to which the sound wave travelled /time taken by the wave

Option 4th is correct

distance traveled / time

Explanation:

Allison wants to calculate the speed of a sound wave.

The speed of the sound wave is the distance traveled divided by the time.

Where, v = speed of sound

d = distance

t= time

Therefore, The formula should she use is, distance traveled / time

The correct answer to the question is : D) Distance travelled / Time.

EXPLANATION:

Before going to answer this question, first we have to understand the speed of a sound wave.

The speed of a sound wave is defined as the rate of distance travelled or the ratio of distance travelled by the wave to the time taken by that wave to cover that distance.

Mathematically speed =

Hence, the correct answer to the question will be the fourth option i.e speed of the sound wave is distance travelled per unit time.

because the speed of propagation of sound wave formula is the quotient of the distance traveled by a sound shaking by the time required on arrival.

because the speed of propagation of sound wave formula is the quotient of the distance traveled by a sound shaking by the time required on arrival. on edguinuity
