Homework Answers
frequency has the formula
F = c /
c = speed = 1482 ms-1
= wavelength = 440 nm = 4.4*10^-7 m
f = 1482 / 4.4*10^-7
f = 3.36818*10^8 s-1
answer => 3.37*10^8 s-1

High-frequency sound waves exhibit less diffraction than low-frequency sound waves do. However, even high frequency sound waves exhibit much more diffraction under normal circumstances than do light waves that pass through the same opening. The highest frequency that a healthy ear can typically hear is 2.0 × 104 Hz. Assume that a sound wave with this frequency travels at 342 m/s and passes through a doorway that has a width of 1.2 m. (a) Determine the angle that locates the...

The relations between wavelength, frequency, period, and speed of propagation apply to all wave phenomena, not just electromagnetic radiation. The C key on a piano has a fundamental frequency of about 256 Hz. What is the corresponding wavelength of the sound waves? (The speed of sound in air varies with temperature but is about 340 m/s at room temperature.)

When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 117 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of...
