Questions
- A sound wave produced by a chime 515 m away is heard 1.50 s later.
(a) What is the speed of sound in air?
(b) The sound wave has a frequency of 436 Hz. What is its period?
(c) What is the wavelength of the sound? - A hiker shouts toward a vertical cliff 685 m away. The echo is heard 4.00 s later.
(a) What is the speed of sound in air?
(b) Why is this speed of sound slightly different from the previous answer?
(c) The wavelength of the sound is 0.750 m. What is the frequency?
(d) What is the period of the wave? - The speed of light in air is 3.00× 108 m/s. If a light wave has a wavelength of 5.80× 10 −^7 m, what is its
frequency?
- transverse wave:A transverse wave is a moving wave that consists of oscillations occurring perpendicular
(or right angled) to the direction of energy transfer - undisturbed position:The equilibrium or rest position of the medium in a wave.
- crest:A crest is the point on a wave with the maximum value or upward displacement within a cycle
- trough:A trough is the opposite of a crest, so the minimum or lowest point in a cycle
- amplitude:The maximum displacement from a zero value during one period of an oscillation.
- wavelength:The distance between corresponding points of two consecutive waves.
- frequency:The number of waves that pass a fixed point in unit time.
- period:A period is the time required for one complete cycle of vibration to pass a given point.
