Student 1: The red light has a higher wavelength (λ) than the blue light. Using the equation v = f * λ, that shows that the red light has a larger velocity (v) as well. Student 2: But both kinds of light should be moving at the same speed, since they are both going through the same medium, space. I think the blue light needs to have a higher frequency than the red light, to make up for the red light’s higher wavelength. Do you agree or disagree with either or both of the students? Explain your reasoning.
Applications Of Reflection Of Light
When a light ray (termed as the incident ray) hits a surface and bounces back (forms a reflected ray), the process of reflection of light has taken place.
Sign Convention for Mirrors
A mirror is made of glass that is coated with a metal amalgam on one side due to which the light ray incident on the surface undergoes reflection and not refraction.
