Since we know the wavelength of light in the two media, we can deduce the effect with pictures. The key is to draw the plane waves as the location of the maximum field values. These crests will be straight lines, but spaced more closely together in the medium with higher index of refraction.
Geometrical Optics (ray optics), treated in the first half of the class. Emphasizes on finding the light path. Especially useful for studying the optical behavior of the system which has length scale much larger than the wavelength of light, such as:
Define the electromagnetic spectrum, and describe it in terms of frequencies and wavelengths. Describe and explain the differences and similarities of each section of the electromagnetic spectrum and the applications of radiation from those sections.
Draw a simplified electromagnetic spectrum, indicating the relative positions, frequencies, and spacing of the different types of radiation bands. List and explain the different methods by which electromagnetic waves are produced across the spectrum.
In general, the index of refraction varies with the wavelength of light. Thus, incident light generally scatters in multiple directions at the boundary between two different media, an effect known as dispersion .
11 Οκτ 2016 · In a vacuum all wavelengths of light (electromagnetic radiation) travel at the same speed along the same path taking the same time. Different wavelengths travel at different speeds in other mediums; this is called dispersion.
31 Αυγ 2019 · The wavelength λ of waves between the parallel plates cannot be larger than twice the distance a between the plates. The maximum wavelength λ = 2a corresponds to the limiting case k z = 0 for λ = λ G. Such a wave guide acts like a filter that allows only waves with a wavelength λ < λ G to pass.
