# Ch 11: Physics Lab Experiments: Matter & Light

Watch video lessons and learn about the different aspects of how light works and how matter changes. The quizzes that follow each lesson can help you gauge your comprehension of the materials.

## Physics Lab Experiments: Matter & Light - Chapter Summary and Learning Objectives

Our ability to see objects around us is largely due to how light reflects off of and passes through those objects. In fact, with an advanced understanding of how light moves and works, we can use light and shadows to make accurate measurements of distant objects. Of course, to understand the properties of light, you also need to know about matter in all of its forms, including solids, liquids, and gases. This chapter is designed to teach you:

• The basic properties of light
• The buoyancy and density factors of solids
• How temperature affects matter
• How light moves through a lens

Video Objective
Ernest Rutherford's Gold Foil Experiment: Physics Lab Measure the shape and size of objects through indirect means, and then replicate Ernest Rutherford's gold foil experiment.
Elasticity of Solids: Physics Lab Determine the elasticity levels of solids by examining their density and crystal structure.
Density & Buoyancy of Objects: Physics Lab Identify factors that contribute to the likelihood of an object floating or sinking in liquids.
Pressure Change & Volume of a Gas: Physics Lab Experiment with gas-filled balloons and determine how changes in pressure increase or decrease the balloon's volume.
Specific Heat of Water & Metals: Physics Lab Define the concept of specific heats, discover the specific heats of common metals and water, and show the similarities between common metals and water based on these findings.
Water Phase Changes: Physics Lab Explore the changes of water from solid ice to liquid water and finally to vapor.
Investigating Light Properties: Physics Lab Analyze how opaque and transparent objects affect beams of light, and study how light reflects off of mirrors at various angles.
Light Color: Physics Lab Use filters to view the light spectrum, identify how receptors in the human eye see light, investigate how color blindness affects how the eyes see light, and dissect white light through the use of prisms.
Reflection & Refraction of Light: Physics Lab Test how the reflection of light differs on a flat mirror compared to a curved one, and then look through a lens to explore light refraction.
Ray Diagrams & Lenses: Physics Lab Utilize ray diagrams to show how light travels through the lens of an eyeball, discuss how light and sight work to form images, and go over the two most common types of eyeglasses.
Diffraction & Interference: Physics Lab Review double slit interference and single slit diffraction patterns.
