Chem topic 1 Flashcards
Light is a type of energy called what
electromagnetic radiation
electromagnetic waves consist of what
wavelength and amplitude
what does wavelength and amplitude determine
colour, brightness
what is frequency
the number of wavelengths that pass a particular point in space over a period of time
what does smaller wavelength do in terms of frequency? what about a larger wavelength?
SWL-larger freq
LWL-smaller freq
range of possible frequencies is known as what
electromagnetic spectrum
give the order of electromagnetic spectrum from lowest to highest energy
radio, microwave, infrared, visible light, ultraviolet, xray, gamma ray
what is spectroscopy
study of the interaction between light and matter
what does light emitted and absorbed mean
falls back to a lower energy state and E is neg, excites to an energy state and E is pos
what are the names for the nfinals being 1 2 3 4?
lyman, balmer,paschen,brackett
what is an interference pattern? what two types are there?
characteristic property of waves, constructive/destructive
what is a node
region of space where there is no electron density
whats an orbital
a region where there is a high probability of finding an electron
