non-scattering‚ absorbing medium‚ the intensity of the light after passing though the medium is given by: (1) Where I(0) is the intensity at s=0‚ a is the absorption cross section of a single particle for radiation of wavelength ‚ n is the number density of the medium‚ and s is the length of the medium. We can apply the relationship to solar radiation passing though the atmosphere. From equation 1‚ we find that ‚ the transmissivity of the slant path of the atmosphere at a given wavelength is

Premium Density Viscosity Fundamental physics concepts
Procedures Objective In this experiment‚ the objectives were to use a balance and measure the volume of the liquids. Theory In the experiment‚ three calculations were used. These are the density‚ relative error and the standard deviation. Density is refers to the mass (m) per unit volume (V) of a material and is often represented by the symbols d or ρ‚ where d = m/V. The density of an object changes with pressure and temperature. Second‚ relative error is a calculated by finding the difference

The samples were categorized as liquids and solids. Under the liquid samples were the subcategories of water and liquids other than water. Subcategories for solid samples were regularly-shaped and irregularly-shaped. All in all there were seven samples‚ namely water‚ isopropyl alcohol‚ coconut oil‚ wooden block‚ marble‚ pebbles‚ and an unknown liquid sample. For the density of water‚ a clean and dry 100ml graduated cylinder was weighed and 50ml of water was added into the graduated cylinder. The
