Light and Sight
The Light and Sight Video Tutorial explains the importance of light to vision. Luminous and illuminated objects are contrasted to each other and the role of reflected light in viewing illuminated objects is described. The viewing of images in the mirror is discussed and attention is given to the path that light travels when viewing such images.
The video lesson answers the following questions:
- In what way is light reflection important to sight?
- What is meant by “line of sight” and how is the concept used to determine an image location?

Tutorial on Reflection and the Ray Model of Light, Lesson 1
When you need to quickly review a topic and/or freshen up on a concept, The Tutorial section of our website is your go-to place. There are two pages in particular that complement this video:
The Role of Light to Sight
The Line of Sight
Physics Interactives, Reflection and Refraction, Image Formation by Plane Mirrors
This interactive Tutorial takes the topic a bit further than the video but nonetheless includes some good information and simulations that make it a worthy follow-up to the video.
Teacher Resources
Curriculum Corner, Reflection and Mirrors
Our Curriculum Corner includes in excess of 200 Think Sheets on discrete topics. Each Think Sheet takes a developmental approach to a topic. The one on Light Reflection would make a great in-class follow up for this video.
Concept Builders, The Law of Reflection
The next video in our series is on the Law of Reflection. This Concept Builder is a must-do. Take a peek at it now, whether you're assigning the next video or not.
