Frequency The number of waves

When a wave, such as that on the sea, travels in a particular direction, we can characterize it by a number of parameters - the velocity of travel, its amplitude (the height of the waves), its wavelength (distance between adjacent peaks), and its frequency (the number of waves per unit time). The simplest form of wave to consider is a sine wave, the equation for... 

Free radical a species with an unpaired electron. (22.5) Frequency the number of waves (cycles) per second that pass a given point in space. (12.1)... 

Freezing point. The temperature at which the solid and liquid phases of a substance coexist at equilibrium. (11.8) Frequency. The number of waves that pass through a particular point per unit time. (7.1)... 

Frequency the number of waves (cycles) per second that pass a given point in space. 

V = frequency, the number of waves passing a certain pomt per umt time... 

Hertz, Hz (Section 10.5) A measure of electromagnetic frequency, the number of waves that pass by a fixed point per second. 

Frequency (v), the number of wave cycles (successive crests or troughs) that pass a given point in unit time. If 108 cycles pass a particular point in one second,... 

Electromagnetic waves are usually described in terms of (a) wavelength A (distance between the peaks of waves in cm, unless otherwise specified), (b) wavenumber v (number of waves per cm), and (c) the frequency v (number of waves per second). The three quantities are related as follows ... 

Hz = Hertz, unit of frequency - the number of times a wave oscillates per unit time - measured in cycles per second. 

The wavelength of light can now be related to the frequency, or number of waves passing a given point per second, using the speed of light value ... 

Frequencies in the electromagnetic spectrum can be seen from Figure 9-7 generally to be large. As a result, it is common to use wave numbers instead of Hz or MHz (megahertz). The frequency in wave number is simply the frequency v in Hz divided by c, the velocity of light in cm. Wave-number units are cm-1 and we can think of the wave number v as being the number of wave crests per centimeter. 

Electromagnetic waves are characterized by a wavelength, a frequency, and an amplitude, (a) Wavelength (A) is the distance between two successive wave peaks, and frequency (v) is the number of wave peaks that pass a fixed point per unit time. Amplitude is the height of the maximum measured from the center line, (b) What we perceive as different kinds of electromagnetic radiation are simply waves with different wavelengths and frequencies.
