What happens to wavelength when intensity increases?
The intensity (i.e. photon energy or field strength) is related to the characteristics of the wave by Planck’s constant. i.e. the photon energy is inversely proportional to the wavelength. As the wavelength increases, the energy of the wave decreases (inversely proportional)
Does light intensity affect the wavelength?
The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength. Both Wave 1 and Wave 2 have the same wavelength but different amplitudes. In the spectrum of light that we are familiar with violet has the shortest wavelength while red has the longest.
Does intensity depend on wavelength?
Intensity of light is defined as the energy transmitted per unit area in one unit of time. Suppose a source of light is in the form of a spherical shape and it is emitting a light of some wavelength. This means that the intensity of a wave depends on the amplitude of the wave.
What is the relation between intensity of scattered light and wavelength?
The intensity of scattered light is found to be inversely proportional to the fourth power of wavelength of light. This relation holds when the size of air molecules is much smaller than the wavelength of the light incident.
What happens when you increase the intensity of blue light?
The higher energy blue light ejects electrons with higher kinetic energy compared to the green light. The scientists observed that if the incident light had a frequency less than a minimum frequency ν0\nu, start subscript, 0, end subscript, then no electrons were ejected regardless of the light amplitude.
How do light intensity and wavelength affect what we see?
The color or hue of light depends on its wavelength, the distance between the peaks of its waves. The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness is also somewhat influenced by wavelength. Yellow light tends to look brighter than reds or blues.
What is the difference between intensity and wavelength?
Energy per unit time is measured in watts, so intensity is measured in watts per square meter. For a wavelength of, say 508 nm, the height of the graph gives the intensity of just that part of the light that has a wavelength between 507.5 nm and 508.5 nm.
Does intensity of light affect frequency?
Yes, the intensity depends, in part, on the frequency. if N is the monochromatic photon emission rate (photons per second), ν is the frequency of the photons, and A is the area these photons are hitting.
