Question

dimension of intensity of wave , wavelength , moment if force ​

Answer 1

• Intensity Formula. Intensity is the quantity of energy the wave conveys per unit time across a surface of unit area and it is also equivalent to the energy density multiplied by the wave speed.The formula for intensity is articulated by, Where I is the intensity, P is the power and A is the area of cross section

• The wavelength and the intensity of light are not directly related. The wavelength is directly related to the energy of the light—shorter wavelengths are higher energy and longer wavelengths are lower energy.The brightness is the intensity, whereas the color is the wavelength.

• If intensity of a wave is proportional to frequency, why doesn't sound level, in general, depend on frequency. The loudness of a sound does not seem to depend on frequency. But according to the equation above, intensity DOES depend on frequency.
