A beam of sound waves of a specific frequency and intensity is passed from one medium into another, arriving at the interface at an angle that is not perpendicular to the interface. Identify TWO aspects of this sound wave that will be different about this beam now that it is travelling in the second medium compared to when it was in the first medium. Explain your answer.

Expert Solution

Sound waves similar to light waves undergo reflection and refraction when moving from one medium to another. In both cases Frequency of wave remains unchanged. only the velocity and Wave length does change .

if the angle of incidence i is not perpendicular to the interface , it would undergo reflection and refraction and absorption .

sound waves travelling through undergo refraction as the temperature of air varies .

On a warm day temperature near the ground is more hence the velocity of sound near the ground is more ,resulting in a sound wave bentway from the ground hence the sound wave does not seem to travel so far.

at night the ground is cold hence the velocity of sound near the ground is less , resulting in a sound wave bent towards the ground , hence the sound wave does seem to travel far.speed of sound is directly praportional to temperature , the formula is given by v _air = 331.4+( 0.6*T_C) m/s where T_c is temperarture in celcius.

1. During night time ground cools of quickly

2. waves bendaway from the normal and get back towards the ground

3.music is louder at night

A tuning fork generates sound waves with a frequency of 230 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is46.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s. (Ans in degrees)

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 19 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 29 cm. What is the wavelength of the sound? Express your answer using two significant figures. If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum? Express your answer using two significant...

For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). a) Measurements of the blood flow in the ascending aorta shows a maximum speed of 92.00 cm/sec. Assuming the ultrasound frequency used is 2.000000 MHz (the paper uses 2.25 MHz), calculate the frequency as seen by the blood that is traveling toward the ultrasound transducer at 92.00 cm/s. The transducer, which both transmits and receives the sound...
