A woman is standing in the ocean, and she notices that after a wave crest passes by, five more crests pass in a time of 61.2 s. The distance between two successive crests is 34.6 m. What is the wave's (a) period, (b) frequency, (c) wavelength, and (d) speed?
Properties of sound
A sound wave is a mechanical wave (or mechanical vibration) that transit through media such as gas (air), liquid (water), and solid (wood).
Quality Of Sound
A sound or a sound wave is defined as the energy produced due to the vibrations of particles in a medium. When any medium produces a disturbance or vibrations, it causes a movement in the air particles which produces sound waves. Molecules in the air vibrate about a certain average position and create compressions and rarefactions. This is called pitch which is defined as the frequency of sound. The frequency is defined as the number of oscillations in pressure per second.
Categories of Sound Wave
People perceive sound in different ways, like a medico student takes sound as vibration produced by objects reaching the human eardrum. A physicist perceives sound as vibration produced by an object, which produces disturbances in nearby air molecules that travel further. Both of them describe it as vibration generated by an object, the difference is one talks about how it is received and other deals with how it travels and propagates across various mediums.
![**Wave Characteristics Problem**
A woman is standing in the ocean, and she notices that after a wave crest passes by, five more crests pass in a time of 61.2 seconds. The distance between two successive crests is 34.6 meters. What is the wave's:
(a) Period
(b) Frequency
(c) Wavelength
(d) Speed
**Answers Input Section:**
- **(a)**
- Input: [Number]
- Units: [Select]
- **(b)**
- Input: [Number]
- Units: [Select]
- **(c)**
- Input: [Number]
- Units: [Select]
- **(d)**
- Input: [Number]
- Units: [Select]
**Explanation:**
The problem provides information to calculate the wave's period, frequency, wavelength, and speed using the basic principles of wave dynamics.
- **Period (T):** The time taken between successive wave crests passing by.
- **Frequency (f):** The number of crests passing a point per unit time.
- **Wavelength (λ):** The distance between two successive crests.
- **Speed (v):** How fast the crest is moving, calculated by multiplying the frequency by the wavelength.
