A beam of light, initially travelling in the air, strikes water surface at an angle of 24.5° with the normal. If the speed of light in water is 2.22 × 10^8ms^-1, determine the angle of refraction?​

Your answer is 1.5 hope i  

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
