Difference Between Luminescence and Phosphorescence

Luminescence vs Phosphorescence   Light is a form of energy and to generate light another form of energy should be used. Production of light can occur in several mechanisms like below. What is Luminescence? Luminescence is the process of emitting light from a substance. This emission is not due to heat; therefore, it is a […]

Difference Between Progressive Wave and Stationary Wave

Progressive Wave vs Stationary Wave   Waves are a very important phenomena occurring in real life. The study of waves and vibrations runs a long way back in time. The concepts of stationary waves and progressive waves are discussed in many fields of physics and chemistry. These are discussed in mechanics, acoustics, radar technology, communication […]

Difference Between Ammonium Nitrate and Urea

Ammonium Nitrate

Ammonium Nitrate vs Urea   Compounds containing Nitrogen are commonly used as fertilizers because nitrogen is one of the highly essential elements for plant growth and development. Ammonium nitrate and urea are such nitrogen containing solids. Ammonium nitrate Ammonium nitrate has the chemical formula of NH4NO3. This is the nitrate of ammonia, and it has the following […]

Difference Between Absorption Spectrum and Emission Spectrum

Absorption Spectrum vs Emission Spectrum   Absorption and emission spectra of a species help to identify those species and provide a lot of information about them. When absorption and emission spectra of a species are put together, they form the continuous spectrum. What is Absorption Spectrum? An absorption spectrum is a plot drawn between absorbance […]

Difference Between Fluorescence and Phosphorescence

Fluorescence vs Phosphorescence   When a molecule or atom absorbs energy, it can undergo various changes. Fluorescence and phosphorescence are two such processes. What is Fluorescence? Electrons in an atom or a molecule can absorb the energy in the electromagnetic radiation and thereby excite to an upper energy state. This upper energy state is unstable; […]

Difference Between Red and Blue Litmus Papers

Red vs Blue Litmus Papers   Indicators are a special type of chemicals, which have the ability to change their colors when pH is changing. Therefore, these are known as pH indicators. Some indicators can take different colors to different pH values. For example, pH papers show a range of colors depending on the strength […]

Difference Between Vacuoles and Vesicles

Vacuoles vs Vesicles   A cell is like a bag of chemicals. It is capable of survival and self replication. The cell is separated from the external environment by the cell membrane, which is a very thin membrane. The cell contains various types of organelles in its cytoplasm. These organelles include the nucleus, Golgi apparatus, […]

Difference Between Pollen and Spore

Pollen vs Spore   Diploid spore mother cells give rise to spores. Spores are haploid structures. They are important for reproduction as well as for survival in the unfavorable conditions. Spores are seen as a part of the life cycle of many organisms including plants, fungi, bacteria, algae etc. In plants, depending on the different […]

Difference Between Pollen and Nectar

Pollen vs Nectar   Flower is a highly specialized reproductive shoot. A typical flower has 4 whorls, one after the other, on a stalk. The stalk can be short or long. The two lower whorls are not directly involved in reproduction. Therefore, they are called accessory whorls. Upper two whorls are directly involved in reproduction. […]
