Amplitude, Period and Frequency - Trigonometry - Socratic
The frequency of a wave describes the number of complete cycles which are completed during a given period of time. As such, frequency is a rate quantity which describes the rate of oscillations or vibrations or cycles or waves on a per second basis. A common unit of frequency is the Hertz, abbreviated as Hz. #color(red)("Frequency " = 1 ...
How do you calculate the period and frequency? - Socratic
2018年6月20日 · color(red)("Period " = 1 / " Frequency " or " T = 1 / f Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the …
How do you calculate the frequency of a wave? - Socratic
2018年6月28日 · Well you use an equation for that... Frequency of a wave is given by the equations: 1.f=1/T where: f is the frequency of the wave in hertz T is the period of the wave in seconds 2.f=v/lambda where: f is the frequency of the wave in hertz v is the velocity of the wave in meters per second lambda is the wavelength of the wave in meters For electromagnetic …
How do I find the frequency of a sinusoidal graph? - Socratic
2014年11月18日 · In a sinusoidal model of the form y = a*sin(b(x - c))+d, the period is found by taking (2*pi)/|b|. Frequency is the reciprocal of period. Example: y = 2*sin(3x) would have a period of (2pi)/3, which is one-third the length of the "normal" period of 2pi. Another way to describe this change from the Parent function would be to say that the graph would cycle through 3 times by …
Calculations with wavelength and frequency - Chemistry - Socratic
If the frequency is the same, how will this affect the wavelength of the waves? A certain shade of blue has a frequency of #7.32 * 10^14# #Hz#. What is the energy of exactly one photon of this light?
What is the formula for frequency? - Socratic
2015年5月7日 · Frequency, f, is the number of oscillations in the unit of time (1 second) and is given as the reciprocal of the Period, T, (which is the time taken for one complete oscillation) so: f=1/T measured in s^-1 called Hertz. Frequency is also related to wavelength, lambda, as: c=lambda*f where c is the speed of light.
How can I calculate the wavelength of electromagnetic radiation?
2014年8月9日 · The equation that relates wavelength, frequency, and speed of light is c = lambda*nu c = 3.00xx10^8 "m/s" (the speed of light in a vacuum) lambda = wavelength in meters nu = frequency in Hertz (Hz) or 1/"s" or "s"^(-1)". So basically the wavelength times the frequency of an electromagnetic wave equals the speed of light. FYI, lambda is the Greek letter lambda , …
Hardy-Weinberg Equation - Biology - Socratic
This means that these #98# also have the homozygous recessive genotype, the frequency of which is equal to #q^2#. To determine what the actual frequency is, simply divide #98/200=0.49#. We now know that #q^2=0.49#. However, we wish to find the frequency of the population that is heterozygous, which is equal to #2pq#. So, we must find both #p ...
How to find frequency of rotational motion without knowing …
2017年4月2日 · omega = 10 (radians)/s I assume that we are referring to a rigid object that rotates at a constant angular frequency omega around some axis of rotation. We know the linear speeds v_1=3 m/s and v_2=2 m/s at two points 1 and 2 on the rotating solid, and we know that the radii (distance from the axis of rotation) r_1 and r_2 at these two points are related as r_2 …
How do you find the period and frequency of a sine function?
2018年7月14日 · The period is =2pi ad the frequency is =1/(2pi) The period T of a periodic function f(x) is f(x)=f(x+T) Here, f(x)=sinx.....(1) Therefore, f(x+T)=sin(x+T) =sinxcosT ...
