Lesson: Refraction of Light Physics • Second Year of Secondary School

Students will be able to

• recognize that light travels at different speeds in different media,
• recognize that the wavelength of light is different in different media but that frequency is constant,
• recognize that the greater the refractive index of a substance, the slower light travels in the substance,
• recognize that light incident nonnormally on a media boundary changes propagation direction,
• define angle of refraction,
• use Snell’s law to determine incident and refracted angles and values of refractive index.
