Question

Diagram (a) When very bright light shines on this transparent material, a small amount of light is reflected at point X. (i) On diagram 2, draw the reflected ray from point X. incident ray 64° refracted ray​

Answer 1

Answer:

11 Diagram 1 shows what happens when light is incident on a piece of transparent material. ray of light not to scale Diagram 1 (a) When very bright light shines on this transparent material, a small amount of light is reflected at point X Q On diagram 2, draw the reflected ray from point X. 12) incident ray 64" refracted ray Diagram 2 G) Measure the angle of refraction at point X on diagram 2. (1) angle degrees (II) State the formula linking refractive index, angle of incidence and angle of refraction (1) (iv) Show that the refractive index of the transparent material is about 1.7 (2) (V) State the formula linking refractive index and critical angle. 11) (vi) Calculate the critical angle for the transparent material. (2) critical angle = degrees
