1

EM Waves

Transverse Waves without a medium. They travel in electrical and magnetic fields

New cards
2

Electromagnetic Spectrum

name for the range of electromagnetic waves when placed in order of frequency and wavelength.

New cards
3

Radio Waves

lowest frequency and longest wavelength

New cards
4

Gamma Rays

highest frequency and the shortest wavelength

New cards
5

Visible Lights

the only EM Waves that we can see

New cards
6

Cosmic Rays

another high-energy radiation from energetic cosmic events in space. These rays are produced by stars such as the sun. One of the examples of Cosmic Rays are aurora borealis or the northern lights.

New cards
7

X-Rays

are wavelengths with 10 nm to 0.01m, these rays have enough energy to penetrate deep into tissues and can cause damage to cells

New cards
8

Rays

light waves that travels in straight lines

New cards
9

Reflection

is the change in direction of a wave front at an interface between two different media so that the wave front returns into the medium from which it originated

New cards
10

Refraction

is the change in direction of wave propagation due to a change in its transmission medium

New cards
11

Dispersion

a phenomenon in which the phase velocity of a wave depends on its frequency

New cards
12

Diffraction

is the spreading of light after it passes around the edge of an object

New cards
13

Absorption

the light wave could be absorbed by the object, in which case its energy is converted to heat (THERMAL ENERGY).

New cards
14

Human Eye

produces a real, inverted image in the retina.

New cards
15

Camera

forms a real and inverted image on a photographic film

New cards
16

Compound Microscope

forms a real, inverted, and enlarged image near the focus of the eyepiece

New cards
17

eyepiece of A Telescope

works as magnifier, therefore Telescopes produces enlarged images
