This KS3/4 physics worksheet explores the fundamentals of waves, light and sound through a mix of clear explanations, engaging questions and real-world applications. Students will classify transverse and longitudinal waves, label and describe key wave properties, and use the wave equation to calculate speed, frequency and wavelength. They will work with amplitude–time graphs, link pitch and loudness to frequency and amplitude, and apply their understanding to everyday examples such as lightning and thunder, colour filters, and why black clothes feel warmer in sunlight. The electromagnetic spectrum is covered in detail, with ordering by frequency, wavelength relationships, and calculation of frequencies for red and blue light, alongside a research-style challenge on practical uses for each type of wave. The worksheet contains recall, application, and calculation questions, encouraging independent thinking and problem-solving. Full answers are included to support marking, peer assessment, or self-checking. Designed to take around 40–50 minutes, it is ideal for classwork, homework, or targeted revision.
