Study Notes
Optics Test Review
- Reflection:
- The angle of incidence equals the angle of reflection.
- The incident ray, reflected ray, and the normal are all in the same plane.
- Electromagnetic Spectrum (least to most energetic):
- Radio waves
- Microwaves
- Infrared
- Visible light
- Ultraviolet
- X-rays
- Gamma rays
- Electromagnetic Waves and Their Applications:
- X-rays: Medical imaging
- Ultraviolet light: Vitamin D production
- Radio waves: Telecommunication, radar, TV remote control
- Infrared light: Theatre concert effects
- Microwaves: Microwave ovens, radar, TV remote control
- Gamma rays: Cancer treatment
- Visible light: Medical imaging, theatre concert effects
- Colours of Visible Light:
- Red, orange, yellow, green, blue, indigo, violet
- Primary Colours:
- Red, blue, green
- Secondary Colours:
- Cyan, yellow, magenta
- Combining Primary Light Colours:
- Combining all primary colours creates white light.
- Light Filter Combinations:
- A green filter followed by a yellow filter with white light will result in yellow light.
- Complementary Color:
- The complementary color of red is cyan.
- Concave Mirrors
- An image can be upright or inverted
- For an upright image, the object must be placed between the focal point and the mirror.
- For an inverted image, the object must be placed beyond the focal point.
- Convex Mirrors
- The image is always virtual, smaller, and upright, regardless of the object's position.
- Convex mirrors use in parking garages:
- Convex mirrors provide a wide field of view and a reduced virtual image.
- Refraction:
- Light bends as it travels from one medium to another.
- The speed of light changes as it travels through different mediums.
- Total Internal Reflection:
- Light from a slower medium to a faster medium undergoes total internal reflection when it bends past the critical angle and reflects back into the slower medium.
