An electromagnetic wave of frequency 2.30 × 10^14 hz propagates in carbon tetrachloride with a speed of 2.05 x 10^8 m/s. what is the wavelength of the wave in carbon tetrachloride? show all work and include units of measure.
the index of refraction for water at 20° c is 1.333 and the index of refraction for air at 20° c is 1.00293. find the angle of refraction for a ray of light that enters a bucket of water from air at an angle of 30.0° to the normal. show all work and provide units of measure.

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
