Understanding the Wave Equation: Velocity, Frequency, and Wavelength1 objectives
- Use knowledge of formulae relating velocity, frequency and wavelength.
Understanding Transverse and Longitudinal Waves1 objectives
- Communicate the key features of differences between transverse and longitudinal waves.
How Sound Wave Properties Change When Moving Between Media1 objectives
- Develop knowledge and skill in the way changes, in velocity, frequency and wavelength, in transmission of sound waves from one medium to another, are inter-related.
Wave Behaviour at Material Interfaces: Reflection, Transmission, and Absorption1 objectives
- Communicate the key features of the effects of reflection, transmission, and absorption of waves at material interface.
Converting Sound Waves and Solid Vibrations1 objectives
- Develop secure knowledge and application of describe, with examples, processes which convert wave disturbances between sound waves and vibrations in solids
(Higher) Limited Frequency Range of Processes and Human Hearing1 objectives
- Account for why such processes only work over a limited frequency range, and the relevance of this to human hearing.
Understanding Transverse and Longitudinal Waves: Water Ripples and Sound1 objectives
- Communicate the key features of the way ripples on water surfaces are used to model transverse waves whilst sound waves in air are longitudinal waves, and how the speed of each may be measured.
Waves: Energy Transfer Without Matter Transfer1 objectives
- Communicate the key features of evidence for the cases of ripples on water surfaces and for sound waves in air that it is the wave that travels and not the water or the air.
Understanding Electromagnetic Waves1 objectives
- Retrieve and apply knowledge of electromagnetic waves are transverse and are transmitted through space where all have the same velocity.
How Electromagnetic Waves Transfer Energy1 objectives
- Account for electromagnetic waves transfer energy from source to absorber.
Understanding Frequency and Wavelength in the Electromagnetic Spectrum1 objectives
- Use knowledge of the relationships between frequency and wavelength across the electromagnetic spectrum.
Understanding the Electromagnetic Spectrum1 objectives
- Communicate the key features of the main groupings of the electromagnetic spectrum and that these groupings range from long to short wavelengths and from low to high frequencies.
Visible Light: A Small Part of the Electromagnetic Spectrum1 objectives
- Communicate the key features of our eyes can only detect a limited range of the electromagnetic spectrum.
Light as an Electromagnetic Wave1 objectives
- Retrieve and apply knowledge of light is an electromagnetic wave.
Practical Uses of Electromagnetic Waves1 objectives
- Develop knowledge and skill in examples of some practical uses of electromagnetic waves in the radio, microwave, infrared, visible, ultraviolet, X-ray and gamma ray regions.
Hazardous Effects of Ultraviolet, X-rays, and Gamma Rays on Human Tissues1 objectives
- Communicate the key features of the way ultraviolet waves, X-rays and gamma rays can have hazardous effects, notably on human bodily tissues.
Using Waves for Internal Exploration (Higher Tier)1 objectives
- Develop secure knowledge and application of explain, in qualitative terms, how the differences in velocity, absorption and reflection between different types of waves in solids and liquids can be used both for detection and for exploration of structures which are hidden from direct observation, notably in our bodies
Producing and Inducing Radio Waves with Electrical Circuits (Higher)1 objectives
- Retrieve and apply knowledge of radio waves can be produced by, or can themselves induce, oscillations in electrical circuits.
Interaction of Electromagnetic Waves with Matter (Higher)1 objectives
- Retrieve and apply knowledge of different substances may absorb, transmit, refract, or reflect electromagnetic waves in ways that vary with wavelength.
Refraction and the Velocity of Electromagnetic Waves (Higher)1 objectives
- Account for the way some effects are related to differences in the velocity of electromagnetic waves in different substances.
