Attochemistry: Is Controlling Electrons the Future of Photochemistry? Controlling matter with light has always been a great challenge, leading to the ever-expanding field of photochemistry. In addition, since the first generation of light pulses of attosecond (1 as = 10-18s) duration, a great de...
What is a joule in physical chemistry?Kinetic energy:Kinetic energy is the energy that an object possesses while in motion. This is in contrast to potential energy, which is the energy that an object holds while not in motion.Answer and Explanation: ...
What Is the Steady State Theory of the Universe? What Is a Pair-Instability Supernova or a PISN? What Is an Electron-Capture Supernova? What Is Stellar Nucleosynthesis via Nuclear Fusion?
A wave in chemistry and physics usually refers to a propagating disturbance that is periodic. Therefore it has a certain wave shape that repeats over time, with the length of this shape being termed the wavelength {eq}\lambda {/eq}. The amount of repetitions of this wave ...
Statement : wavelength of (I) line of Humphry series is more than (I) line of Lyman series in H-atom Explanation :ΔE=hcλ. View Solution The wavelength ofHαline in Balmer series is View Solution Ratio of the wavelengths of line of Lyman series and first line of Balmer series is. ...
However, a wave's wavelength is directly related to its wave number. In fact, a wave number is sometimes described as the number of wavelengths in a given distance. The wave number can also be defined as the reciprocal of the wavelength, as expressed through the following formula. ...
