Understanding Wavelength and Frequency1 objectives
- Develop knowledge and skill in wavelength and frequency.
Understanding the Wave Equation: Velocity, Frequency, and Wavelength1 objectives
- Communicate the key features of and apply the relationship between wavelength, frequency and wave velocity.
Understanding the Wave Speed Equation1 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.
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.
Understanding Wave Motion: Water Ripples and Sound Waves1 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 they all have the same velocity.
Energy Transfer by Electromagnetic Waves1 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.
The Limited Range of Human Vision in 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 the Electromagnetic Spectrum1 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 (UV), 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.
Generation and Detection of Radio Waves using 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.
(Higher) Refraction and the Speed of Electromagnetic Waves1 objectives
- Account for the way some effects are related to differences in the velocity of electromagnetic waves in different substances.
Atomic Nuclei and Charge1 objectives
- Retrieve and apply knowledge of atomic nuclei are composed of both protons and neutrons, that the nucleus of each element has a characteristic positive charge.
Isotopes and Nuclear Mass1 objectives
- Retrieve and apply knowledge of atoms of the same elements can differ in nuclear mass by having different numbers of neutrons.
Understanding Isotopes and Nuclear Notation1 objectives
- Apply the conventional representation for nuclei to relate the differences between isotopes.
Unstable Nuclei and Radioactive Emissions1 objectives
- Retrieve and apply knowledge of some nuclei are unstable and may emit alpha particles, beta particles, or neutrons, and electromagnetic radiation as gamma rays.
Understanding Radioactive Decay: Changes to Nuclei from Particle Emission1 objectives
- Develop knowledge and skill in the emission of alpha particles, beta particles, gamma radiation and neutrons to possible changes in the mass or the charge of the nucleus, or both.
Writing Balanced Nuclear Equations for Radioactive Decay1 objectives
- Apply names and symbols of common nuclei and particles to write balanced equations that represent radioactive decay.
Understanding and Balancing Nuclear Decay Equations1 objectives
- Develop knowledge and skill in equations representing the emission of alpha, beta or gamma radiations in terms of the masses, and charges of the atoms involved.
Electron Arrangements and Energy Levels1 objectives
- Retrieve and apply knowledge of in each atom its electrons are arranged at different distances from the nucleus, that such arrangements may change with absorption or emission of electromagnetic radiation and that atoms can become ions by loss of outer electrons.
Radiation from Atoms and Nuclei1 objectives
- Retrieve and apply knowledge of changes in atoms and nuclei can also generate and absorb radiations over a wide frequency range.
Half-life and the Random Nature of Radioactive Decay1 objectives
