A student saw a rainbow outside after school. The next day the student decided to model how rainbows form. The student shines white light through a glass prism and sees how the light splits up into many colors.
Which two ways does the student’s model need to be changed to better show how rainbows are formed?
The prism should have a round shape because raindrops are round.
D
The prism should be made of water instead of glass because rain is made of water.
