waves

• Wavelength is the distance between two consecutive points on a wave that are in phase.
• Transverse waves involve oscillation perpendicular to the direction of wave motion, while longitudinal waves involve compression and rarefaction parallel to the direction of wave motion.
• The speed of sound is affected by temperature, with warmer air causing the molecules to move faster and increasing the speed of sound.
• Electromagnetic waves are waves that can travel through a vacuum.
• Light travels at different speeds through different materials due to refraction.
• The speed of sound depends on temperature and density of medium through which it travels.
• Sound travels more slowly through solids than liquids or gases due to the stronger intermolecular forces present in solids.
• Reflection occurs when a wave bounces off an object without being absorbed.
• Radio waves have the longest wavelength and lowest frequency, while gamma rays have the shortest wavelength and highest frequency.
• Infrared radiation has longer wavelengths than visible light but shorter wavelengths than microwaves.
• Sound waves require a material medium to propagate, such as solids or liquids.
• Diffraction is the spreading out of waves as they pass around obstacles.
• Ultraviolet (UV) radiation has wavelengths shorter than those of violet light.
• Waves transfer energy from one place to another without moving matter itself.
• Transverse waves oscillate perpendicular to the direction of propagation (e.g., light).
• Waves transfer energy but not matter from one place to another.
• X-rays are used in medical imaging and cancer treatment.
• Ultraviolet (UV) radiation is used in tanning beds and sunscreens.
• Gamma rays are emitted during nuclear decay and can penetrate matter deeply.
• Gamma rays are emitted by radioactive materials and can be dangerous if not shielded properly.
• Infrared radiation has longer wavelengths than visible red light.
• Electromagnetic waves do not need a medium to travel and can travel through space.
• X-rays have very short wavelengths and high frequencies.
• Radio waves have long wavelengths, while gamma rays have short wavelengths.
• Microwave radiation is used in microwave ovens and satellite communication.
• Radio waves have long wavelengths and low frequencies.
• Radio waves have the longest wavelengths and lowest frequencies among all types of EM waves.
• Radio waves have very long wavelengths and low frequencies.
