In Young's experiment, the source is red light of wavelength 7xx10^(-7)m. When a thin glass plate of refractive index 1.5 at this wavelength is put in the pat
Wavelength:Wavelength is a property of light. Light may have a higher or lower wavelength which will correspond to differences in colour. For example, red light has a longer wavelength than purple light.Answer and Explanation: The wavelength range of visible light is approximately from 380 nanomet...
What is the wavelength of a 2.0 eV red photon? What is the wavelength (in nm) of a yellow light with a frequency of 5.23 \times 10^{14} Hz? What color of visible light has the highest energy? Which color of the visible spectrum of the electromagnetic waves will travel the fastest in...
Red is the colour with the longest wavelength; that means that as it travels through air molecules, it gets diffused(扩散)less than other colour, so it can be seen from a greater distance. Yellow has a shorter wavelength than red but a longer wavelength than green. This means that red is...
For remote sensing and GIS applications, the wavelength of light is the determining aspect of its color. For instance, light with wavelengths of 400-500 nanometers (nm) is blue light, 500-600 nm is green, and 600-700nm is red, which is referred to as the visible portion of the electro...
Each color in the visible light spectrum has a different wavelength. Red and orange light waves, for instance, have longer wavelengths, while blue and violet light have much shorter wavelengths. It's the shorter wavelengths of light that are more likely to be scattered — or absorbed and re-...
