Light Wave How do light waves behave around corners (Draw what you. The most amount of diffraction happens when the wavelength is a similar size to the gap. Reflection, Refraction, and Diffraction Mini-Labs. (a picture would help to explain this)ĭiffraction: Waves spread out as they enter an aperture (gap). Using the laws of reflection, the direction in which reflected light travels can be predicted. Remember that in reflection the angle of incidence (this is. As it slows down it changes direction, meaning that the angle that it is travelling at changes - the angle becomes closer to the normal. Refraction Reflection occurs when light rays bounce off object. Reflection: This is when a wave hits a surface (e.g light hitting a mirror) and is bounced back. Hence, both can split white light in to its component wavelengths. Refraction: When light travels from air into another material (such as glass) at any angle other than normal (perpendicular), it slows down. Both diffraction and refraction are wavelength dependant. Remember that in reflection the angle of incidence (this is the angle that the initial wave makes from the normal), is the same as the angle of reflection (the angle that the reflected wave makes from the normal). The reflection and refraction of light explains how people see images, colour and even optical. Reflection: This is when a wave hits a surface (e.g light hitting a mirror) and is bounced back. All waves will reflect and refract in the right circumstances. On the diagram it is useful to mark on a line for 'normal', this is a straight line that is perpendicular (makes a 90 degree angle) with a surface. Depending on the position of secondary wavelets, they may be reflected or continue to propagate into the medium, undergoing refraction. It can also be helpful to draw diagrams of each to help you to remember the difference. These are all properties of waves and their definitions are useful to remember for exams.
