Instructional Ideas

• Post the video after the lesson about making calculations based on wavelength, frequency, and speed of light for pupils to access if they need a reminder

Classroom Considerations

• Assumes an understanding of the formula wavelength x frequency = speed
• YouTube video requires Internet access
• The fourth in a series of 14 lessons

• This video is hosted on YouTube

Pros

• Quick and clear explanation of using the formula
• Includes units that need converting

Cons

• Seems to make a leap in concepts from the previous lessons in the series
