Question

In a measurement, the critical angle is measured to be 44.6 degrees. The index of refraction of the material is Answer In a measurement, the critical angle is measured to be (38.8+/-1.5) degrees. The error on the index of refraction of the material is (NB the error on the angle must be in radians) Answer A combination divergent lens-convergent lens is used to produce an image. The object is placed 6.3 cm from the divergent lens (fd--5cm). The convergent lens ( fe- 5 cm) is 9.3cm behind the divergent lens. The distance between the object and the image is ( in cm) Answer

Explanation / Answer

Index of refraction = 1/ sin(theta) = 1/ sin44.6 = 1.424
