How do you increase the intensity of light? Light intensity represents the amplitude of light with the same wavelength, and light wavelength is a property of light that determines the colors of the light (Sliney, 2016). Is light intensity the same as wavelength? if you consider light is wave, intensity is related to light radiation energy and frequency is the number of waves per second. Is light intensity the same as frequency?Īnswer: Light is electromagnetic radiation and exhbits dual nature, wave and particle. Since light is also a wave, its intensity will depend on the amplitude of the wave. This means that the intensity of a wave depends on the amplitude of the wave. Does light intensity depend on frequency?

In the SI system, it has units watts per square metre (W/m2), or kg⋅s−3 in base units. In physics, the intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy. It is the measure of the wavelength-weighted power emitted by a light source. Light intensity refers to the strength or amount of light produced by a specific lamp source.
