• Straight-Line Travel: Cathode rays travel in straight lines, casting sharp shadows.
• Negatively Charged: Composed of negatively charged particles, specifically electrons, deflected by electric and magnetic fields.
• Deflected: When subjected to electric or magnetic fields, cathode rays are deflected towards the positive plate, confirming their negative charge.
• Production: Cathode rays are produced at the cathode and move towards the anode in a vacuum tube.
• Speed: Despite high speeds, cathode rays move slower than light.
• Heating Effect: When struck, cathode rays cause heating, indicating their energy.
• Penetration: Cathode rays can penetrate thin metal foils, demonstrating their material nature.
• Fluorescence: Cathode rays cause certain materials to glow when struck.
• Ionization: They can ionize gases, contributing to chemical reactions.
• Mass: Cathode ray particles are extremely light, making them extremely light.
• X-ray Production: Colliding with heavy metals produces X-rays.\n
