Study Notes
Properties of Light
- Light properties include intensity (brightness), direction, frequency (color), and polarization.
- Light behaves predictably in various circumstances, revealing its characteristics.
Physics Lab Overview
- Required materials: flat mirror, paper, pencil, ruler, protractor, straight pin/thumbtack, laser pointer.
- The lab involves measuring angles and observing the reflection of light.
Lab Procedure Highlights
- Fold paper and draw a line; position mirror upright on the line.
- Place a pin or thumbtack on a dot drawn on the paper in front of the mirror.
- View the pin in the mirror from different angles; draw lines to represent light paths.
- Extend the lines until they meet, indicating where light would bounce off the mirror.
- Measure the angles of incidence and reflection, recording both.
Observations and Analysis
- Light travels in straight lines and specific directions.
- The behavior of light with mirrors creates the illusion that objects are behind the mirror.
- The angles of incidence (incoming) and reflection (outgoing) are equal, illustrating the Law of Reflection.
Color and Frequency of Light
- Light can be categorized by frequency; red light has low frequency, while blue light has high frequency.
- White light is a mixture of all colors, which can be separated into a spectrum (rainbow effect).
