Science g10 2nd quarter reviewer

Long-term exposure can damage eyes and skin; contributes to the greenhouse effect; and elevates temperatures.

Overexposure can cause skin cancer, eye damage, and immune suppression; harms plant growth.

Can harm living cells, potentially leading to cataracts and skin burns.

Can kill living cells, and increase risk of radiation poisoning and cancer.

Light bouncing off a surface.

Mirrors with curved surfaces.

A curved mirror that bulges away from light, causing light rays to converge.

A curved mirror that bulges towards the light, causing light rays to diverge.

Different forms of energy that travel as waves, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Used in radar, phone calls, cable TV, ovens, and medical treatments (microwave ablation).

Higher temperatures create shorter infrared waves. Useful for remote controls and night vision.

Visible light is perceived as colors: ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet).

The sun is a major source of UV radiation, which comes in types UVA, UVB, and UVC.

Used for medical imaging (bones, teeth), security scans, and industrial inspections.

Gamma rays come from celestial events like stars and supernovae, used in cancer treatment.

Visible light powers photosynthesis, but also has harmful effects like eye damage and breakdown of materials.

The relationship between electricity and magnetism where a changing magnetic field induces an electric current in a conductor.

A device that converts one form of energy into another, often used for audio or other signals.

The range of all types of electromagnetic radiation, from radio waves to gamma rays, ordered by frequency and wavelength.

A wave that is created by accelerating electric charges and that has both electric and magnetic components that travel together.

A device that converts mechanical energy into electrical energy by rotating a coil within a magnetic field.

The property of materials that allows them to attract or repel other magnetic materials.

Michael Faraday's experiment demonstrating the generation of an electric current from a changing magnetic field.

Hans Christian Oersted's finding that a current-carrying wire creates a magnetic field.
