prism
(i) Describe one thing that happens to the blue light​

Answer 1

When Carlos shines blue light into a prism one thing that happens to blue light is:

• The blue light diffracts i.e it bends while escaping out of the prism.
• Diffraction happens due to light changing its medium. Here the blue light enters from a gaseous to a solid medium and later moves from a solid to a gaseous medium. Simply put, the blue light changes its speed when entering mediums of different refractive indexes.
• Blue light has the shortest wavelength amongst all the colours that combine to make white light. This means the blue light diffracts (bends) the most out of all of them.
• There will be no dispersion of colours because ideally,  the blue light must consist of only one frequency.
