- Could I have help with this physics problemA flat piece of glass covers the top of a vertical cylinder that is completely filled with water. If a ray of light traveling in the glass is incident on the interface with the water at an angle of a = 36.0°, the ray refracted into the water makes an angle of 49.9° with the normal to the interface. Part A What is the smallest value of the incident angle a for which none of the ray refracts into the water? Express your answer in degrees.

HẢ = Value Units %D Submit Request Answer Part CThe observer in figure is positioned so that the far edge of the bottom of the empty glass (not to scale) is just visible. When the glass is filled to the top with water, the center of the bottom of the glass is just visible to the observer. Find the height, H, of the glass, given that its width is W=4.8cm. Express your answer using two significant figures.You (height of your eyes above the water, h = 1.80 m) are standing 2.00 m from the edge of a 2.50-m-deep swimming pool (Figure 1). You notice that you can barely see your cell phone, which went missing a few minutes before, on the bottom of the pool. The index of refraction of water at this temperature is 1.333.
