Terms
undefined, object
copy deck
- Red, Orange, Yellow, Green, Blue, Indigo, Violet
- What are the colors that make up white light?
- light reflects and the image is reflected
- What happens to light as it strikes a mirror?
- the sun
- Where do electromagnetic waves come from?
- no, invisible
- Is most electromagnetic radiation visible to the human eye?
- the only reflected color that is not absorbed
- When white light strikes an object, what shows us what the color of the object is?
- light rays spread apart, making the image appear smaller
- What happens to light as it passes through a concave lens?
- black
- shows when all white light is absorbed
- white
- shows when all light is reflected
- light waves (visible spectrum), ultraviolet waves, x-rays, infrared rays, radio waves, gamma rays, and microwaves
- What are the forms of electromagnetic radiation?
- convex mirror
- curves outward, reflects images smaller
- convex lens
- a lens that is thicker in the middle than at the edges
- transparent
- a material that allows light to be transmitted
- shadow
- absence of light
- mirrors and lenses
- have opposite effects
- lenses
- curved transparent material tha bends light to enlarge or clarify an image
- it splits into the visible spectrum, or, rainbow
- What happens to white light when it passes through a prism?
- transit/transmit
- passed through a medium
- translucent
- a material that allows some light to be transmitted
- light microscope
- has 2 convex lenses on each side of an opaque tube
- frequency
- the number of waves which pass a given point in a certain amount of time - usually in seconds
- reflecting telescope
- has a large concave lens at one end and a small convex at the other that magnifies the image produced by the lens
- luminous
- lit up
- absorb
- taken in and most often changed to heat energy
- yes
- Can light travel through a vacuum?
- image
- a picture of the light source that light rays make in bouncing off a polished shiny surface
- concave lens
- a lense that is thicker at the edges than in the middle
- light rays spread apart causing images to appear larger
- What happens to light as it passes through a convex lens?
- amplitude
- the measurement from the average wave height to the crest on the trough (1/2 the distance from the crest to trough)
- refraction
- the bending of light rays as they pass from one substance into another
- mirror
- a material that reflects all light that hits it
- 300,000 km/sec
- How fast does light travel?
- in straight pathes
- How do light waves travel?
- electromagnetic radiation
- radiation consisting of electromagnetic waves
- the bottom lense causes the image to look larger and the top convex bends it down even more making the image large and clear
- Wat happens when light passes through a light microscope?
- rays or beams
- What is another name for light waves?
- concave mirror
- curves inward, reflects images larger
- opaque
- light is absorbed by the material - creates shadow and gives no view at all
- ray
- beam of light
- reflection
- the bouncing of a light wave off a surface
