Suppose you want to demonstrate the doppler effect for deep-water waves, using a 7.37 hz source moving toward a stationary observer. how fast would the source have to move through the water if the frequency of the waves seen by the observer is to be eight times the frequency of the source?
absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.
emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
the unit of the measure =
the property that is quantified by the energy needed per of material to raise the temperature by one.
si unit of energy = joule (j)
si unit of temperature = kelvin (k)
si unit of mass of material = kilogram (kg)
the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.
the unit of specific heat is
