Question

The car in the drawing is moving to the left at 35 m/s. The car's horn continuously emits a 2.20 × 102 Hz sound. The figure also shows the first two regions of compression of the emitted sound waves. The speed of sound is 343 m/s.56. What is the wavelength of the sound in the direction of motion of the car? A) 1.40 m B) 1.56 m C) 1.70 m D) 1.93 m E) 35 m Ans: A

Answer 1

The wavelength of the sound in the direction of motion of the car is 1.56 m. The correct answer is option: B) 1.56 m.

Step-by-step explanation:

The wavelength of a sound wave can be calculated using the formula:

Wavelength = Speed of Sound / Frequency

In this case, the speed of sound is given as 343 m/s and the frequency is given as 2.20 x 10^2 Hz. Plugging these values into the formula, we get:

Wavelength = 343 m/s / (2.20 x 10^2 Hz)

= 1.56 m

Therefore, the correct answer is option B) 1.56 m.
