What are the main differences between transverse and longitudinal waves?
In transverse waves, the particles move perpendicular to the direction of the wave (e.g., light waves), while in longitudinal waves, the particles move parallel to the direction of wave propagation (e.g., sound waves).
How do seismic waves help scientists understand the Earth's interior?
Seismic waves travel through the Earth and are refracted or reflected differently by different materials. By studying these waves, scientists can infer the composition and structure of the Earth's layers.
What is the role of lenses in forming images?
Lenses bend (refract) light to focus it onto a screen or retina, forming clear images. The curvature and shape of the lens determine the focal length and type of image produced (real or virtual).
How do electromagnetic waves differ in terms of frequency and wavelength?
Electromagnetic waves range from radio waves with long wavelengths and low frequencies to gamma rays with short wavelengths and high frequencies. As the frequency increases, the energy of the wave also increases.
Why is visible light only a small part of the electromagnetic spectrum?
Visible light occupies a small range of wavelengths and frequencies between infrared and ultraviolet radiation. The entire electromagnetic spectrum encompasses a much wider range of frequencies, including radio waves, X-rays, and gamma rays.
What is the difference between a transverse wave and a longitudinal wave in terms of particle motion?
In a transverse wave, the particles move at right angles (perpendicular) to the direction of wave motion, whereas in a longitudinal wave, the particles move parallel to the direction of wave motion.
What is the purpose of using radio waves in wireless communication?
Radio waves are used in wireless communication because they can travel long distances, can be easily modulated to carry information, and do not require a medium to propagate, allowing communication over large areas.
Explain how sound waves are produced and how they travel.
Sound waves are produced by the vibration of particles in a medium (such as air, water, or solids). These vibrations cause compressions and rarefactions that travel through the medium, transferring energy from one particle to the next.
What happens when a wave is reflected from a surface?
When a wave is reflected from a surface, the angle of incidence (the angle between the incoming wave and the normal) is equal to the angle of reflection (the angle between the reflected wave and the normal). This is known as the law of reflection.
What are some practical uses of X-rays and gamma rays in medicine?
X-rays are commonly used for imaging bones and tissues, while gamma rays are used in cancer treatment to target and destroy cancerous cells through radiation therapy.
