American companies lead in the development of such low wavelength light, which is difficult to produce.

They are sensitive to red, green and blue wavelength light.

The drug is triggered by light of a specific wavelength.

This is long wavelength light, beyond the detection of our eyes or a telescope like Hubble.

The analysis of this system is simplified if we consider light of a single wavelength.

Very small wavelength light (ultraviolet and beyond) is more difficult to control and measure.

The use of relatively long wavelength light allows it to penetrate into the scattering medium.

These dyes needed to be excited by light of a certain wavelength in order for them to light up.

If they only have long wavelength light hitting them (as at sunrise or sunset) they appear red.

They lack the opsin gene that would allow them to detect short wavelength light, which includes the colors blue and green.
