What is the relationship between refractive index and wavelength? v = f. Combining the above expression for velocity with the definition of index of refraction, we find a relationship between the wavelength = v/f in a medium and the wavelength 0 = c/f in vacuum: In the above equation, the frequencies cancel because frequency does […]

Do autoclaves kill everything?
Do autoclaves kill everything? The short answer: no. Autoclaves are capable of killing all types of microorganisms such as bacteria, viruses, and even spores, which are known to survive at high temperatures and can only be killed at temperatures around 130°C. Why autoclaving is the best method of sterilization? Wet Heat (Autoclaving) This is a […]
What happens to current during charging and discharging of a capacitor?
What happens to current during charging and discharging of a capacitor? Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards […]

How is cubical expansion calculated?
How is cubical expansion calculated? “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T). What is an example of anomalous Behaviour […]
What role do planetesimals play in the origin of the planets?
What role do planetesimals play in the origin of the planets? A planetesimal is small bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are when planetesimals join together through collisions and through the force of gravity to form larger bodies. Because they have their gases they […]
What percentage of CO2 emissions are man made?
What percentage of CO2 emissions are man made? In fact, carbon dioxide, which is blamed for climate warming, has only a volume share of 0.04 percent in the atmosphere. And of these 0.04 percent CO2, 95 percent come from natural sources, such as volcanoes or decomposition processes in nature. The human CO2 content in the […]
What are the sources of thermal pollution?
What are the sources of thermal pollution? Some of the important sources of thermal pollution are nuclear power and electric power plants, crude oil refineries, steel melting factories, coal fire power plant, boiler from industries which release large amount of heat to the water bodies leading to change in the physical, chemical and biological characteristics […]
What kind of charging occurs when you slide your body across a plastic surface?
What kind of charging occurs when you slide your body across a plastic surface? Electrostatics: When a person slides across a plastic surface, the plastic produces a net negative charge and your body surface a net positive charge. What will happen if you switch the battery so that the positive end is on the right […]
