I think the answer is save as
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.
Answer:
Option (B) is the correct answer of this question.
Explanation:
Packet analyzer is a software application or set of infrastructure capable of unencrypted and recording communication that travels through a virtual system of a computer system.A packet analyzer used to detect network activity is recognized as a broadband monitoring system.
A packet analyzer is a code application that is used for monitoring, intercepting, and recording http requests with the help of a virtual interface.
Other options are incorrect because they are not related to the given scenario.
Answer:
"async" attribute
Explanation:
the async attribute is used on the html script tag, it is a Boolean attribute indicating that the browser should, if possible, load the script asynchronously and then parse it as soon as it’s downloaded.
