A narrow beam of white light can be split up into different colours by a glass prism. The correct explanation is that
From the diagram, the correct equation for the refractive index n of the medium is
A diverging lens of focal length 30cm produces an image 20cm from the lens. Determine the object distance
An object is placed at 5.6 x 10\(^{-4}\)m in front of a converging lens of focal length 1.0 x 10\(^{-n}\)m. The image formed is
In the diagram above, which of the angles \( \theta _1 \) , \( \theta _2 \) , \( \theta _3 \) and \( \theta _4 \) is the angle of deviation of the ray of light passing through the glass prism XYZ?
