Physics Chapter 6 Waves describing waves transverse and

Physics Chapter 6 – Waves – describing waves, transverse and longitudinal , wave speed Name the parts of the waves: Define the terms: L= Amplitude – B: M= N= Describe the sounds below: A: Wavelength – C: D: O= P= Frequency – Define the term wave and give an example of how we can use waves. Time period State the equation that links wave speed, wavelength and frequency. Include the units. Define the term longitudinal waves, draw a diagram and give an example: Define the term transverse waves, draw a diagram and give an example: State the equation that links time period and frequency. Give units.

Physics Chapter 6 – Waves – reflection and refraction Complete the ray diagrams to show reflection and refraction. Include the labels to shows incidence, reflection and refraction ray and the normal line. Describe what happens to the light ray when it goes from air to a solid. Describe what happens to the light way when it goes from a solid to air. State the law of reflection. Define the terms: HIGHER TIER: Describe what wavelength dependence is and give an example. Normal: Reflection: Describe what refraction is: Absorbed: Transmitted: HIGHER TIER: Describe what a wave front is and draw a diagram to demonstrate it.

Physics Chapter 6 – Waves – electromagnetic waves Fill in the gaps and add an arrow to your diagram to show longest wavelength, lowest frequency and low energy: Radio Microwave Infrared State the wavelength ranges of the waves in electromagnetic spectrum: R I V U X G HIGHER TIER: Describe how radio waves can be produced in electrical circuits and also the effect that radio waves may have on electrical circuits HIGHER TIER: Describe the difference in refraction for electromagnetic waves. Visible light Ultra violet X-Ray Gamma Using the space below to state the properties of the electromagnetic spectrum. Include its uses, the hazards and the practical applications. HIGHER TIER explain why each electromagnetic wave is suitable for its practical application and the reflection and refraction of radio signals.

Physics Chapter 6– Waves –maths skill and 2 x required practical. Rearrange the equation to show frequency for the equation period and frequency. Describe a method used to investigate the speed of waves in a ripple thank and speed of sound on a stretched spring. Include a diagram of your set up. Describe a method used to investigate the amount of radiation absorbed or radiated by a surface depends on the nature of that surface. Include a diagram of your set up. Explain why increasing the speed increases either the frequency of wavelength. State the variables for the waves investigation: Independent variable – Dependent variable – Control variable – State expected results. State errors to do with the wave investigation. Write a risk assessment for this practical. Include the risk, hazard and control for at least 1 risk.
