Generally when light of a certainwavelength falls on a subwavelength aperture, it is diffracted isotropically in all directions evenly, with minimal far-field transmission.

A short laser pulse at a certainwavelength between 532-770 nm is generated to irradiate the target tissue to induce acoustic pressure waves.

One example is when a certainwavelength of light is put onto certain channels, the blockage in the pore is relieved and allows ion transduction.

To cut down light pollution and enhance contrast observers employ "nebular filters" designed to admit certainwavelength and block others.

This means that a telescope with a certain mirror diameter can theoretically resolve up to a certain limit at a certainwavelength.

They offer a selectable band gap for the propagation of a certainwavelength, thus they resemble a semiconductor, but for light or photons instead of electrons. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Photosensitisation causes skin inflammation by a mechanism involving a pigment or photodynamic compound, which when activated by a certainwavelength of light leads to oxidation reactions in vivo. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Spectral lines are less dominant as light is produced across the spectrum, usually peaking, or centered, on a certainwavelength. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The net result is that only for certain wavelengths does the deformed surface cause a net increase in pressure at the neck and a decrease in pressure at the swell. The absorption of light by life at certain wavelengths could then produce spectral signatures which are distinctive. Many materials selectively absorb certain wavelengths of light.
