Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.
Suitable for separate and combined science higher level students. Science AQA GCSE and Edexcel IGCSE - 22-23rd December and 2-3rd January. Check them out now! This topic is included in Paper 1, Paper 2, Paper 3, Paper 4, Paper 5 and Paper 6 for IGCSE CAIE Physics.
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials. Emphasis is on both light and mechanical waves. Examples of models could include drawings, simulations, and written descriptions. Assessment is limited to qualitative applications pertaining to light and mechanical waves.
- Transparent, Translucent, or Opaque? In the Can You See Through Me? lesson, students experiment with materials to see how they absorb, scatter, transmit, or reflect light.
- Casting Shadows. What happens when you walk down the street and the sun is in front of you? A shadow appears behind you! Objects that block light cast shadows.
- Reflections in a Mirror. In the Mirror, Mirror on the Wall... lesson, students experiment to see how reflective surfaces like mirrors change the direction of light.
- Colors of a Rainbow. In the How Many Colors in a Rainbow? activity, students use a pan of water, the sun, and sheets of colored paper to create rainbows.
May 24, 2024 · The wave equation included physical constants from both electricity and magnetism, and extracting the wave speed from this equation resulted in a number Maxwell was already familiar with – the speed of light. It is traditional to denote this speed with a lower-case 'c': c = 3.0 ×108m s (2.1.1) (2.1.1) c = 3.0 × 10 8 m s.
