- You have a convex, spherical mirror (as shown below) with a radius of curvature R=3.33m (the distance of the "Radial Line" shown in the image below). You shine light rays that are parallel to the principlal axis of the mirror as shown below that reflect in such a way that it appears all rays originated at the a point called the focal point of the mirror (F). Along the principal axis of the mirror, how far behind the mirror is the focal point (in meters)? It is important to point out that the focal point of convex mirrors, strictly speaking, is negative. This is because the object appears to originate from behind the mirror. Here, don't worry about the negative sign. Give a positive answer.A light ray is incident perpendicular to the left face of the shown prism made of glass (n = 1.6). What is the largest value of the angle p such that the light ray is totally reflected at the far right face if the prism is surrounded by air?

- Diamond is known for being a particularly brilliant stone. The reason behind this is its peculiarly high index of refraction, n = 2.4. A ray of light within a diamond hits the diamond-air (n = 1) interface. Calculate the critical angle for diamond such that the ray be totally internally reflected. Critical angle for diamond-air interface = 0 Once you have determined this, compare the critical angle to the one in the figure below, which is for a glass-air interface? Knowing that glass has a smaller refractive index than diamond, which material will have a larger critical angle. n2=1 n1 =1.5 39° 90° 41.8° 45° 45° Difference between the cirtical angles between the diamond-air and glass-air interface is (report the absolute value of the difference) 0 What is the significance of this comparison with regards to the brilliance of diamond?You have a convex, spherical mirror (as shown below) with a radius of curvature R=3.22m (the distance of the "Radial Line" shown in the image below). You shine light rays that are parallel to the principlal axis of the mirror as shown below that reflect in such a way that it appears all rays originated at the a point called the focal point of the mirror (F). Along the principal axis of the mirror, how far behind the mirror is the focal point (in meters)? It is important to point out that the focal point of convex mirrors, strictly speaking, is negative. This is because the object appears to originate from behind the mirror. Here, don't worry about the negative sign. Give a positive answer.
