Step 1
First, let's define the angle of incidence (θ) as the angle between the direction of the sound wave and the normal to the surface of the brick wall. In this case, the angle of incidence is given as 5 degrees. Show more…

A bat emits short pulses of sound at a frequency of $1.60 \times 10^{5} \mathrm{Hz}$ . As the bat swoops toward a flat wall at speed 30 m/s, this sound is reflected from the wall back to the bat. (a) What is the frequency of sound incident on the wall? (b) Consider the wall as a sound source at the frequency calculated in part (a). What frequency of sound does the bat hear coming from the wall?
A bat emits short pulses of sound at a frequency of $1.60 \times 10^{5} \mathrm{Hz} .$ As the bat swoops toward a flat wall at speed $30 \mathrm{m} / \mathrm{s},$ this sound is reflected from the wall back to the bat. (a) What is the frequency of sound incident on the wall? (b) Consider the wall as a sound source at the frequency calculated in part (a). What frequency of sound does the bat hear coming from the wall?
A bat flies at a steady speed of $4 \mathrm{~m} / \mathrm{s}$ emitting a sound of $f=90 \times 10^{3} \mathrm{~Hz}$. It is flying horizontally towards a vertical wall. The frequency of the reflected sound as detected by the bat will be (Take velocity of sound in air as $330 \mathrm{~m} / \mathrm{s}$ ) (a) $88.1 \times 10^{3} \mathrm{~Hz}$ (b) $87.1 \times 10^{3} \mathrm{~Hz}$ (c) $92.1 \times 10^{3} \mathrm{~Hz}$ (d) $89.1 \times 10^{3} \mathrm{~Hz}$
