Name three radiations and their wavelength range which are invisible and beyond the violet end of the visible spectrum.

State the name and the range of wavelength of the invisible electromagnetic waves beyond the red end of the visible spectrum

Name the region just beyond (i) the red end, and (ii) the violet end, of the spectrum.

Wavelength of the visible spectrum ranges from

Name three properties of ultraviolet radiations which are similar to visible light

Assertion : The increase in wavelength due to doppler effect is termed as red shift. Reason : In red shift, a wavelength in the middle of the visible region of the spectrum moves towards the violet end of the spectrum.

Name the radiations which can be detected by a thermopile.

Give the range of the wavelength of those electromagnetic waves which are visible to us.

Name the radiations : whose wavelength range is from 100 Å to 4000 Å (or 10 nm to 400 nm).

The range of wavelength of the visible light is

The wavelength of light in the visible region is about 390nm for violet color, about 550nm (average wavelength) for yellow green colour and about 760nm for red color. What are the energies of photon in eV at the (i) violet end (ii) average wavelength yellow-green color and (iii) red end of the visible spectrum? ("Take " h=6.63xx10^(-34)Js and 1eV=1.6xx10^(-19)Js)
