That would depend what information is available. One common equation is: speed = wavelength x frequency. However, in a practical situation, it may be easier to actually measure the wavelength and (for example) the frequency, and then make deductions about the wavelength, than the other way round.
The equation to calculate the speed of an object is speed = distance / time. This equation gives the rate at which an object is moving over a given distance in a specific amount of time.
The equation used to calculate average speed is distance traveled divided by the time taken to travel that distance. It is represented as: Average Speed = Total Distance / Total Time.
The equation used to calculate energy is E = mc^2, where E represents energy, m is the mass of the object, and c is the speed of light in a vacuum. This equation, formulated by Albert Einstein in his theory of relativity, shows the relationship between mass and energy.
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
The equation used to measure wave speed is: Wave speed = frequency x wavelength
The equation to calculate the speed of an object is speed = distance / time. This equation gives the rate at which an object is moving over a given distance in a specific amount of time.
The equation used to calculate average speed is distance traveled divided by the time taken to travel that distance. It is represented as: Average Speed = Total Distance / Total Time.
The equation used to calculate the distance something travels is given below . we know, speed = distance /time . distance = speed X time in meters /km /or any other unit of length.
The rate of disappearance equation is used to calculate how quickly a substance is used up or changed in a chemical reaction. It helps determine the speed at which the reaction is happening.
The equation used to calculate energy is E = mc^2, where E represents energy, m is the mass of the object, and c is the speed of light in a vacuum. This equation, formulated by Albert Einstein in his theory of relativity, shows the relationship between mass and energy.
The emission wavelength equation used to calculate the specific wavelength of light emitted by a substance is c / , where represents the wavelength, c is the speed of light in a vacuum, and is the frequency of the light emitted.
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
The equation used to measure wave speed is: Wave speed = frequency x wavelength
If speed is constant:distance = speed x time If speed is not constant, an integral has to be used.
The evaporation equation used to calculate the rate of water loss is: Evaporation Rate (Surface Area) x (Evaporation Coefficient) x (Temperature Difference) x (Wind Speed)
The equation used to calculate the amount of electrical energy used is: Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours).
(Initial downwards speed (m/s)) + (9.81m/s²)x(Time it has been falling(s)) = Downwards speed in metres per second.
