What is the unit for wavenumber?
Wavenumber in most physical sciences is a wave property inversely related to wavelength, having SI units of reciprocal meters(m−1). Wavenumber is the spatial analog of frequency, that is, it is the measurement of the number of wavelengths per unit distance, or more commonly 2π times that, or the number of radians of phase per unit distance. Application of a Fourier transformation on data as a function of time yields a frequency spectrum; application on data as a function of position yields a wavenumber spectrum. The exact definition varies depending on the field of study. http://en.wikipedia.org/wiki/Wavenumber
What is the unit for work and how is it defined in the context of physics?
The unit for work in physics is the joule (J). Work is defined as the transfer of energy that occurs when a force is applied to an object and it moves in the direction of the force.
What is the fundamental unit of charge and how is it defined in the context of physics?
The fundamental unit of charge is the elementary charge, denoted as e. In physics, it is defined as the charge of a single proton or electron, which is approximately 1.602 x 10-19 coulombs.
What is a coulomb and how is it defined in the context of electric charge?
A coulomb is the unit of electric charge in the International System of Units (SI). It is defined as the amount of charge that passes through a conductor in one second when a current of one ampere is flowing.
What is the unit of weight in physics and how is it defined?
The unit of weight in physics is the Newton (N). It is defined as the force exerted on an object due to gravity.
The x-axis of an infrared spectrum is in units of wavenumber-- wavenumber is?
wavenumber is directly proportional to energy. It is inversely proportional to wavelength. I think wavenumber has the unit of m-1

Why wavenumber used in ir?
Wavenumber is used in infrared (IR) spectroscopy because it provides a direct measure of the frequency of molecular vibrations, making it a convenient way to express energy levels. It is defined as the number of wavelengths per unit distance, typically presented in units of reciprocal centimeters (cm⁻¹). This scale allows for a more straightforward comparison of spectral features and is inversely related to wavelength, facilitating the identification of functional groups in molecules based on their characteristic absorption bands. Using wavenumber also simplifies the mathematical relationships between energy, frequency, and wavelength in the context of molecular spectroscopy.

What are three properties of a simple crystal lattice?
Exemples of properties: structure, cell dimensions, lattice energy.
How do atoms relate to molecules?
The atom is the smallest unit of an element that retains the chemical properties of that element. A molecule is defined as a unit of at least two atoms held together by very strong chemical bonds.

What is a Unit of matter that has all the properties of an element?
An atom is a unit of matter that has all the properties of an element. It is the smallest unit of an element that retains the chemical properties of that element.
Is luster defined as the amount of mass per unit volume?
No, the density is defined as the amount of mass per unit volume.
Intensity of a sound?
Sound intensity or acoustic intensity(I) is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
