Amplitude of the wave.
Speed, wavelength, frequency, period, amplitude, intensity.
i think it is speed
Speed in waves is typically measured by calculating the distance a wave travels in a given amount of time. The speed of a wave is often expressed in meters per second or kilometers per hour. It can be affected by factors such as the wavelength and frequency of the wave.
Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
Longitudinal waves can be measured by using instruments like a microphone, which detects changes in air pressure caused by the waves. The amplitude of the waves corresponds to the intensity of the sound, while the frequency is measured in hertz (Hz) and represents the pitch of the sound. Additionally, the speed of sound in a medium can be determined by measuring the time it takes for a sound wave to travel a known distance.
Hope speed is needed in miles per second. Its speed is 1,86,000 miles per second
The question is not quite clear. The speed of electromagnetic waves has been measured, in a great number of experiments of increasing precision and accuracy over the past 150 years, and is now known correctly to within 5 parts per billion.
The four properties that all waves have are amplitude (height of the wave), wavelength (distance between two consecutive points), frequency (number of waves passing a point in a given time), and speed (how fast the wave is moving).
The speed of sound cannot be measured in a vacuum because there is no medium for sound waves to travel through in a vacuum. Sound requires a medium such as air, water, or solids to propagate.
They are measured on the Richter scale.
