Title: Waves 04 September 201804 September 2018 Today we will be learning about waves. By the end of the lesson you will be able to: Explain what physicists mean by waves, giving examples of each type and uses for electromagnetic waves (D) Draw a transverse and longitudinal wave and correctly label amplitude, wavelength and frequency, giving the appropriate units for each term where appropriate (S) Use key ideas about waves to explain why a candle flame moves when placed in front of a speaker (C)

Waves Watch the film clip: At the end you will need to tell me all you can about the two different types of waves; Transverse Longitudinal What do waves transfer from one place to another?

Title: Waves 04 September 201804 September 2018 What types of waves are there? Slinky demonstration Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Title: Waves 04 September 201804 September 2018 Draw a longitudinal wave into your book. Label a point of compression Label a point of rarefaction Which waves are longitudinal waves? Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Pit stop Progress – Can you explain this? Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Title: Waves 04 September 201804 September 2018 Draw a transverse wave into your book. Remember a transverse wave oscillates at right angles to its direction of travel Which waves are transverse waves? Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Wave Motion Wave motion as shown as a snapshot in time. Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Wavelength This is the distance (usually in metres) between one peak and the next. In other words it is the distance of one complete cycle of the wave. Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Amplitude This is the distance from zero displacement to a peak or zero displacement to trough. Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Period The time taken for one complete wave to pass a point.. Measured in Seconds (s) Use absorb and get boys to count for a minute then calculate – works out at about 1.6ish per second Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Frequency The number of complete waves that pass in one second. Measured in Hertz (Hz for short.) Can you work out the relationship between Period & Frequency? Use absorb and get boys to count for a minute then calculate – works out at about 1.6ish per second Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary

Waves of various frequencies. Which has the highest frequency? The lowest? Which has the longest period? The shortest? Today we are learning the names, types and uses of waves, and explaining some uses using key vocabulary
