Dispersion Of White Light by a Glass Prism: When a beam of white light is passed through a glass prism‚ it is split up into a band of colours called spectrum. This is called dispersion of white light. The spectrum of white has the colours violet‚ indigo‚ blue‚ green‚ yellow‚ orange and red (VIBGYOR). The red light bends the least and the violet light bends the most. A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion of sunlight by water

The Colors of India “Taste is colored not just by the gustatory properties of the food itself‚ but its smell‚ sound‚ and appearance as well as by expectations… (Len Tiu Wright‚ 1).” In India‚ every corner turned is a plunge into cultural diversity. The people‚ the landscape‚ the aroma-infused air; to us it seems so exotic‚ but most of them probably don’t think twice about their divergent surroundings. That’s because‚ “while in India‚ living with cultural diversity is living in an environment

Light is just one portion of the various electromagnetic waves flying through space. The electromagnetic spectrum covers an extremely broad range‚ from radio waves with wavelengths of a meter or more‚ down to x-rays with wavelengths of less than a billionth of a meter. Optical radiation lies between radio waves and x-rays on the spectrum‚ exhibiting a unique mix of ray‚ wave‚ and quantum properties. At x-ray and shorter wavelengths‚ electromagnetic radiation tends to be quite particle like

Title: The success of photosynthesis in geranium leaves using visible light wavelengths obstructed by black paper‚ and red‚ blue‚ and green translucent filters. I. Abstract Photosynthesis is a process in which plants use light‚ water‚ and carbon dioxide to produce sugars‚ water and oxygen. Chlorophyll a and chlorophyll b‚ in the chloroplasts of a leaf‚ are responsible for absorbing wavelengths of light for use in photosynthesis with red and blue wavelengths being optimal. Testing

Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor
