1. Indoor pests such as mice and other rodents are sensitive to ultrasonic sound waves (sound waves above the human range of frequency detection). Some companies have
produced (allegedly) rodent repellant devices that emit ultrasonic waves with
frequencies of approximately 45 kHz (1 kHz = 1000 Hz). Assuming a speed of sound of
344 m/s, determine the wavelength of these sounds waves.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
