In GCSE Physics, we study two main types of waves - transverse and longitudinal waves. Transverse waves are waves where the vibrations are perpendicular to the direction of wave travel, such as waves on a string or electromagnetic waves. Longitudinal waves have vibrations parallel to the wave direction, like sound waves.
All waves have fundamental properties:
Waves exhibit important phenomena like reflection, refraction, and diffraction when they interact with boundaries or obstacles. Reflection occurs when waves bounce off surfaces, while refraction is the change in direction due to a change in medium. Diffraction is the spreading out of waves around obstacles.
Problem: A wave has a frequency of 5 Hz and a wavelength of 2 m. Calculate its wave speed.
Solution:
The electromagnetic spectrum consists of waves ranging from radio waves to gamma rays, including visible light. Each type has unique properties and applications, from radio communication to medical imaging. Exposure to high-energy radiation like X-rays and gamma rays can be harmful and requires safety precautions.
Sound waves are longitudinal pressure waves that travel through mediums like air, water, and solids. They have applications in ultrasound imaging, echo sounding (sonar), and studying seismic waves like P-waves (longitudinal) and S-waves (transverse) generated by earthquakes.
