Visible light
ELECTROMAGNETIC SPECTRUM
Radio waves: Used in communication (radio, TV, Wi-Fi). :
-
-
Infrared waves: Felt as heat, used in night vision and remote controls.
-
Visible light: The only part humans can see, ranging from red (longest wavelength) to violet (shortest).
Ultraviolet rays: Can cause sunburn, used in sterilization.
-
Gamma rays: Emitted by radioactive materials and nuclear reactions, highly energetic.
-
Applications
Communication:
Radio waves – AM/FM radio, TV, cell phones.
Microwaves – Wi-Fi, satellites, radar.
Infrared (IR) – Remote controls, fiber optics.
Medical & Health: X-rays –Bone scans, security checks.
Gamma rays – Cancer treatment, sterilization. Infrared – Thermal imaging.

Wave properties
-
Waves are disturbances that transfer energy from one point to another without the transport of matter. The key properties of waves include wavelength, frequency, amplitude, and speed. These properties determine how waves behave and interact with their surroundings.
-
-
-
For visible light, different wavelengths correspond to different colors.
-
-
-
-
-
Higher frequency waves have more energy, while lower frequency waves have less.

Wave Behavior
Wave behavior is how waves reflect, refract, diffract, and interfere with their surroundings.
-
-
-
🔹 Interference:
Waves overlap, creating patterns of constructive (amplification) and destructive (cancellation) interference.
