It is not the wavelength or frequency that determines light absorption- it is the energy of the photon that matters. The energy of incident light should match the excitation energy of the chromophore. The medium itself can also affect light absorption by electronically interacting with the chromophore. Wavelength plays a role in diffraction and therefore ...

Wavelength-frequency relation is $\lambda=\frac{c}{\nu}$ or $\nu\cdot \lambda=c$ in vacuum. In some refractive media you can substitute $c$ with speed of light at corresponding medium, essentially nothing changes. Speed determines the product of wavelength and frequency, not their ratio, as you suggested. Hence at different speeds frequency and wavelength ...

In the context of human vision, wavelength and frequency are not mutually exclusive, but given by the first equation you pointed out in the question. That is, whenever the range of human vision is given they are not assuming that wavelength and frequency can change independently.

What is myopia? Myopia, a.k.a. near-sightedness, is a refractory error. Refraction is the process by which the optical system focuses images of objects on the retina, which are then transmitted to the visual cortex of the brain to be interpreted as vision. The major components of refraction are the cornea, lens, and axial eye length (distance from the ...

For a bit of background, this test was devised by Nobuyuki Kayahara and it was originally thought that it shows the dominance of one part of the brain to the other. This was later on discarded as a misconception (reference). It is now widely believed that the clockwise - counter-clockwise rotation is a phenomenon called Bistable perception (Reference 1 and ...
