Solved in 3 steps with 3 images
- For a concave mirror, if the object distance is less than the focal length, the image is virtual, upright, and enlarged. O True False At least three rays of light are needed in order to find out where the image is formed. O True O False Total interhal reflection can occur when light travels from vacuum to an optical medium with higher index of refraction. O True False The reason that a prism can produce a colorful spectrum from a white light source is that its index of refraction is a function of wavelength. O True FalseWhich statement about the Refraction of light waves is correct? All of theses are correct. O Refraction occurs because light travels at difference speeds in different materials. O Refraction is a process where light bends as it travels from one material to another. Refraction can be used to create a telescope.solve correctly. I will rate accordingly.
- As we saw in the video in step 1, total internal reflection can occur for cases where a light ray attempts to travel from a high index to low index medium. However, it can only occur for particular ranges of incident angles. The lowest possible incident angle for which total internal reflection occurs is called the critical angle. With = 1.50 and n₂ = 1.00, use the simulation to find the critical angle (in degrees). 1₂ 7₂. 1' Play around with different values of ₁, ₂, and 8₁. Try to find the critical angle for different values of n₁ and Note that total internal reflection is only possible in cases where n₁ > ₂.Calculate the critical angle for the light traveling from glass (n glass= 1.54) to air (n=1.00). Express your answer in degrees.
