Science Flashcards
○ These are the transfer of energy
○ Anything smaller than an atom
that doesn’t have any mass
Electromagnetic Waves
The waves are compressed and the energy is transmitted
Longitudinal Waves
○ The energy of waves is traveled sideways
○ Transfer of energy that follows a circular motion.
Transverse Waves
longest wavelengths
lowest frequency
Radio Waves
Bouncing back of a ray of light when it strikes a boundary between different media through which it cannot pass.
Reflection
A ray of light bends when it is passing through a transparent media.
Reflection
The angle of incidence = the angle of reflection
Law of Reflection
Each incident ray bounces off in a single direction.
Specular Reflection
A single ray of light scatters in many directions.
Diffuse Reflection
- Formed by mirrors or lenses when light rays pass through the image.
- These are formed due to the actual intersection of light rays.
Real Image
- Light rays do not pass through the point where the image can be seen.
- These are formed due to the imaginary intersection of light rays.
Virtual Image
A curved mirror in which a reflective surface bulges away from the light source.
Produces real images.
Concave Mirror
A curved mirror in which a reflective surface bulges towards the light surface.
Convex Mirror
A lens aberration where the sharpest focus of the lens is on a curved surface in the image space rather than a plane
Field Curvature
Any material with a reflective surfaces that curve inwards
Concave Mirror
It is the distance between the center of a lens or curved mirror and its focus
Focal Length
A double convex lens
Converging Lens
Any material with reflective surfaces that curve outwards
Convex Mirrors
A double concave lens
Diverging Lens
A vector perpendicular to the tangent plane of the mirror surface
Surface Normal
A piece of glass with curved sides for concentrating or dispersing light rays
Lens
The point at which rays meet after reflection or refraction
Focal Point
longer wavelength and higher frequency
than radiowaves
Microwaves
Longer wavelength but shorter than visible light
Higher frequency compared to microwaves
Infrared Waves
Longer wavelength
Higher frequency
——- compared to visible light
UV (Ultra Violet Light)
Longer wavelength than gamma rays but a shorter wavelength than UV light
H8igher frequency compared to UV light
X-Rays
It has the longest wavelength and highest frequency in the electromagnetic spectrum.
Gamma Rays
straight line path of light.
Ray of light
a bunch of rays of light.
Beam of light
