Answer:
vw = fλ
Explanation:
Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. You can also directly sense the frequency of a sound. Perception of frequency is called pitch. The wavelength of sound is not directly sensed, but indirect evidence is found in the correlation of the size of musical instruments with their pitch. Small instruments, such as a piccolo, typically make high-pitch sounds, while large instruments, such as a tuba, typically make low-pitch sounds. High pitch means small wavelength, and the size of a musical instrument is directly related to the wavelengths of sound it produces. So a small instrument creates short-wavelength sounds. Similar arguments hold that a large instrument creates long-wavelength sounds.
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 2. The frequency is the same as that of the source and is the number of waves that pass a point per unit time.
<u>Some recommend way to prove the authenticity of an email:</u>
- The coworker as truthful to the company or organization he or she has to check where the same mail is sent long back to the same sender.
- If search on emails sent item if he sends it will be well and good. Some time backup the mail will be help to proven authenticity of an email.
- Sometimes once mail is downloaded into ms-outlook or lotus domino some time mail persists in the mail server.
- He or she can coordinate with the mail server administrator to possible get a log file of sending mail and he can proceed as a record to management.
Sisters is an autobiographical graphic novel written by Raina Telgemeier as a follow-up to her earlier graphic memoir Smile. It details a long summer road trip taken from San Francisco to Colorado by her family and explores the relationship between Raina and her younger sister, Amara.
