Turning torch on
Light rays from torch
Light rays from torch absorbed and reflected by wall.
It is the reflected light that allows us to see the wall
Light rays from torch absorbed or reflected by object
It is this diffused reflection of the light that allows us to see the wall and object. These reflected rays also allow us to see the back of the object and the wall without direct torch light
No direct light from torch
Shadow of object on wall.
The shadow is higher than the object.
This is due to the angle formed by the light rays hitting and missing the object
We can change the height of the shadow by moving the object and the torch.
Reflection Objectives: 1.Describe how light reflects off rough and smooth surfaces. 2.Explain the law of reflection.
This picture is asymmetrical because the lens and knife aren’t balanced. This picture has direct light also because the light on her hands and the shadow.
LIGHT AND ITS USES. LIGHT RAY STRAIGHT LINE PATH OF LIGHT.
GROUP 8. REFLECTION-REFRACTION How we can teach the students about reflection and refraction:
Properties of Reflective Waves Flat Mirrors. Light travels in a straight line Some light is absorbed Some light is redirected – “Reflected”
Chapter 13-2 Flat Mirrors. Conceptual_Physics/3 1_Reflection/01/sp.ht mlhttp://localhost:26300/ Conceptual_Physics/3 1_Reflection/01/sp.ht.
Light. Artificial Light Can Be Turned Off and On Examples: – Classroom light – Lamp – Flashlight – Light bulbs.
10.3: The Ray Model of Light. TransparentOpaque Translucent Light passes through freely. A small amount of light is absorbed or reflected. Prevents any.
Sound and LightSection 3 Reflection of Light 〉 How do objects interact with incoming light? 〉 Every object reflects some light and absorbs some light.
Interactions of Light With Matter Science: Chapter 3 Mrs. Milliken.
Light: Geometric Optics. The Ray Model of Light The ray model of light assumes that light travels in straight-line path called rays.
1 Lecture 9 Lighting Light Sources Reflectance Camera Models.
Why are things coloured ?. Beam of white light hits Homers head Yellow light reflects in all directions Blue light reflects in all directions Beam of.
Materials: Pasco Light Machine and a Sheet of Graph Paper, reflective surface, concave lens, convex lens.
Reflection and Light Flat Mirrors. Reflection of Light Reflection – the turning back of an electromagnetic wave at the surface of a substance –A good.
Opaque Sun Moon Straight line Stars Shadow Opaque 2 Sun 1 Mirror 6 Straight line 5 Stars 4 Shadow.
Laws of Reflection and Plane Mirror Images. Reflection When light strikes a surface, some is absorbed, the rest bounces off the surface. This is called.
Chapter 4 (8) Light and Optical Systems Light behaves in predictable ways Text book pages Do 7.1 – 7.3 in your workbooks.
Light. These are all LUMINOUS.LUMINOUS What are some sources of light?
Multiplication Find the missing value x __ = 32.
Electromagnetic Spectrum Quiz What did you do to prepare for this quiz?
Shadows in the desert. Shadow A shadow is a region of darkness where light is blocked. It occupies all of the space behind an opaque object with light.
The Ray Model of Light Lesson 4. Light and Matter Light is represented as straight lines called rays, which show the direction that light travels. Ray.
Geometric Optics. Uses wave model of light to explain properties such as reflection and refraction Assumptions of geometric optics - light travels in.
Task 1: 2 mirrors and a nail- observations At 180° we can see 2 nails. The reflection of the nail was repeated 3 times inside of the mirrors. We saw 9.
Types of Surfaces. When light hits different surfaces, it behaves in different ways. Surfaces can be one of three types. Light can pass through a substance,
Behavior of Light. Behavior of Light affects what we see Visible light can travel through the vacuum of space and it can also travel through a medium.
Points, Lines, and Planes. A point is an exact location in space. You are here.
Light Quiz #1 Review of lessons 1-4. Let’s review vocabulary! Read the definition, write the vocabulary word on your whiteboard!! Let’s begin…
Chapter 17 Reflection and Refraction. Ch 17.1 How light behaves at a boundary.
An Introduction to Reflection SNC2D. We Reflect Light None of us generates light in the visible region of the electromagnetic spectrum. We are not sources.
Reflection and Refraction of Light. Reflection of Light Every object absorbs some light and reflects some light Why is the sun different? – The sun makes.
Year Three- Spring Do shadows have feelings? Can your shadow get hurt? Why do shadows look like the object? Is a shadow the same as a reflection?
Unit 4F: Simple circuits: L.O. 1, 2: N.C. 4.1a Unit 6F: How we see things.
The Principles of Heat, Light, & Sound Light To have light, you must have a light source. Sources of light… Sun Fire Light Bulb.
Using the triangle at T the right, find: 1. Sin T Cos T 7 3. Tan X 4. Cos X V 24 X 5. Using the triangle A 18 B at the right, solve for x. Show work!
Light can be reflected, transmitted and absorbed..
All light is a form of energy. That’s because light “radiates”, or spreads out, in all directions from its source. (Such as a light bulb or star).
Light Continued. The light models explain how we… See ____________ See ______________ in objects ______ see around corners See ________ distant objects.
Light. A Dozen Facts About Light Light Fact 1: Light is a form of energy (energy is the ability to make things change),
Reflection of light.. Specula Reflection. Reflection from a mirrored or glossy surface Specula Reflection.
A Brief Look at LIGHT. Light usually travels 4 only in a straight line. 4 This is known as the... Law of Rectilinear Propagation.
Light can be reflected, absorbed or transmitted by objects.

ENERGY UNIT 4. Light energy : mostly comes from the sun. We can use torches and candles. Thermal energy: provides from the sun and fossil fuels (coal,
Science Olympiad Optics Color and Shadows Optics.
Reflections. When a wave reaches a boundary of two media, some or all of the wave will bounce back into the first media You see waves bounce off a pier.
2.8 – Proportions & Similar Figures “I can solve proportions using scale factors.” “I can find missing side lengths of similar figures.”
Wave Interactions. Can you see me now? Transparent materials allow waves to pass through them with little or no distortion Translucent materials allow.
