blue = 400 nm green = 500 nm red = 650 nm1. Tilly would like to perform an experiment to see what makes up light. find the optical density of atransparent block below. All she has is a transparent trapezoidal block (with a n= 1.4 for red light and1.5 for blue), a protractor, paper, a pencil, and a thin sliver of light peeping through the curtains.a. Draw the light passing through the trapezoid and passing back out of it.b. Draw the first two reflections of the beam.c. What is the angle of refraction of the red light?White light700d. Calculate the critical angle of the block (red light).e. What is the speed of the red light in the block?f. What is the frequency of the red light in the block?g. What is the wavelength of the red light in the block?
