Unit 3 Lesson 4 Interactions of Light What happens when light waves interact with matter? Refraction occurs because light changes speed as it enters a medium at an angle. When light slows in a medium, it bends inward, creating a smaller angle. Light waves with shorter wavelengths bend more. ...

Electromagnetic Waves Synchronized electric and magnetic fields moving through space at the speed of light c = 3108 m/s; it is a transverse wave LIGHT is an electromagnetic wave with a wavelength that our eyes are sensitive to (400 nm to 700 nm) [nm (nanometer) = 109 m] Frequen...
7. Gamma rays Electromagnetic radiation that are most energetic and are comprised of light with wavelengths of less than about ten trillionths of a meter and include waves with wavelengths smaller than the radius of an atomic nucleus (1015m). Produced by nuclear processes during...
9.3 What is a sound wave? Sound waves are pressure waves with alternating high and low pressure regions. When they are pushed by the vibrations, it creates a layer of higher pressure which results in a traveling vibration of pressure.
