Correct, frequency never changes. When light slows down in high refractive index materials, only the wavelength changes.thursdaytbs said:"what is the frequency of red light in the air? What is the frequency of red light in the glass?"
is the frequency of a light wave length constant? therefore, the answer would be the same?
"Constant frequency" refers to the number of complete oscillations or cycles of a light wave that occur in a given amount of time. This frequency remains the same regardless of the medium through which the light wave is traveling.
The frequency of a light wave is typically measured in Hertz (Hz), which is equal to one cycle per second. This can be measured using specialized equipment such as a spectrometer or by counting the number of wave peaks that pass a fixed point in a given time interval.
Yes, the color of light is directly related to its frequency. Red light, for example, has a lower frequency than blue light. This is because different colors of light have different wavelengths, and frequency is inversely proportional to wavelength.
Yes, the frequency of a light wave can be changed by altering the energy of the source producing the light. For example, when an object heats up, it emits radiation with a higher frequency, causing the color to change from red to orange to yellow and eventually to blue as the temperature increases.
The frequency of a light wave is directly proportional to its energy. This means that as the frequency increases, so does the energy. This relationship is described by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. This relationship is important in understanding how light interacts with matter, as higher frequency light can have more energy and therefore create more significant effects.
