WebSolution. Begin with the equation of the time-averaged power of a sinusoidal wave on a string: P = 1 2 μ A 2 ω 2 v. P = 1 2 μ A 2 ω 2 v. The amplitude is given, so we need to calculate the linear mass density of the string, the angular frequency of the wave on the string, and the speed of the wave on the string. http://www.sengpielaudio.com/calculator-SoundAndDistance.htm
WebSep 12, 2024 · The intensity \(I(\lambda, T)\) of blackbody radiation depends on the wavelength \(\lambda\) of the emitted radiation and on the temperature T of the blackbody (Figure \(\PageIndex{2}\)). The function \(I(\lambda, T)\) is the power intensity that is radiated per unit wavelength; in other words, it is the power radiated per unit area of the … WebPower is the rate at which energy is transferred. Measured in watts. Beam area is expressed in cm². Therefore Intensity is measured in mW/cm². Intensity is important when discussing bioeffects and safety. Intensity is proportional to the square of the amplitude. So if amplitude is squared, intensity is quadrupled.
WebEach time distance is doubled, intensity is cut by a factor of four. Since each time intensity is cut in half the sound level decreases 3 dB, it follows that doubling distance reduces the sound level by 6 dB. Following the same logic, increasing the distance by a factor of ten reduces the sound level by 20 dB. WebAnswer: I assume that you mean “after passing through a lens”. The intensity of the light is directly proportional to the opening of the lens, as you might expect: the more area, the more light goes through. The intensity of the image formed by the lens also depends on the distance of the image ...
