A bat can detect small objects such as an insect whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 54.5 kHz, and the speed of sound in air is 339 m/s, what is the smallest insect a bat can detect?

A bat can detect small objects, such as an insect, whose size is approximately equal to one wavelength of the sound the bat makes. If bats emit a chirp at a frequency of 5.89 104 Hz, and if the speed of sound in air is 343 m/s, what is the smallest insect a bat can detect? _______ mm

A bat (see the image below) can detect very small objects, such as an insect whose length is approximately equal to one wavelength of the sound the bat makes. If bats emit chirps at a frequency of 59.1 kHz, and if the speed of sound in air is 336 m/s, what is the smallest insect the bat can detect? mm

A bat flying at 3.00 m/s is chasing an insect flying away from it at a speed of 5.00 m/s. The bat emits a 40.0 kHz chirp which is detected by the insect. What is the frequency of sound detected by the insect, assuming that the insect can actually “hear” the chirp emitted by the bat? (The speed of sound in air is 343 m/s.)

1. (10 Marks)A load of 50 N attached to a spring hanging vertically stretches the spring 5.0 cm. The spring is now placed horizontally on a table and stretched 11 cm. (a)What force is required to stretch the spring by that amount? (b) Plot a graph of force (on the y-axis) versus spring displacement from the equilibrium position along the x-axis x(cm) 2. (10 Marks) What are the (a) amplitude, (b) frequency 20 and (c) phase constant of the oscillation...

A bat is chasing a flying bug. The bat is moving at 4.50 m/s, and can only see the bug when the wavelength is larger than its 40.0 kHz chirp. a. What is the smallest size bug the bat can see on a 18°C night? (Answer: 8.54 mm) b. The bat hears an echo at 40.3 kHz off the bug. What is the speed of the bug? (Answer: 3.2 m/s) c. Will the bat be able to catch up with...

5. Reflected waves for detecting objects: Airplane radar, bat echolocation. (Chapter 4, Exercise 15) Airplanes can be located by radar, which detects radio waves reflected back toward a transmitter. In analogous fashion, bats can locate insects by making high-pitched squeaks and listening for echoes. a) Using concepts from this chapter, can you explain why radar works much better with microwaves (typical wavelength 10 cm) than it would in the AM radio band (wavelengths more than 100 m)? b) Can you...
