electromagnetic spectrum wavelength

While all electromagnetic waves travel at the same speed (i.e., velocity 'c' is constant), the type of their radiation differs in the duration of wavelength and consequently their frequencies. An electromagnetic radiation with a long wavelength will have a..

The Action Spectrum is the curve plotted on a graph paper representing the amount of oxygen evolved or the amount of carbon dioxide fixed or any other action of photosynthesis at different wavelengths of light. It has been observed that the photosynthesis occurs maximum in blue..

The frequency of an electromagnetic wave varies inversely with its wavelength. The frequency of a wave of wavelength 92 meters is 207 kilocycles per second. Find the frequency of the wave whose wavelength is 36 meters. => 16 kilocycles per second or 529 kiloc..

They do not require any medium for propagation; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter waves travel with different veloc..

where 'h' is proportionality constant, universally referred to as Planck's constant. It has a fixed value of: h = 6.63 x 10 3 4 joule.sec or h = 3.99 x 10 - 1 3 kJ sec mol - 1 . This relation was found to be valid for all types of electromagnetic radiation. The total amount of energy emit..

The solar spectrum of electromagnetic waves include energy packed heat generating waves called radiation waves. As they lie beyond red colour waves of visible spectrum, they are also called 'infra-red rays'. These infrared rays lie in the wave length range of 700..

Photosynthetic Pigments - Molecules of chlorophyll-a, chlorophyll-b, carotene and xanthopyhll are situated in the thylakoid membranes. For light energy to be used by living systems, it must first be absorbed. A pigment is any substance that absorbs light. Chlorophyll, the pigment that makes leaves ..
