Questão 4
Questão
Electromagnetic wave: A [blank_start]transverse[blank_end] [blank_start]wave[blank_end] composed of an oscillating [blank_start]electric[blank_end] field and a magnetic [blank_start]field[blank_end] that [blank_start]oscillates[blank_end] [blank_start]perpendicular[blank_end] to the electric field.
Responda

transverse
-
electric
-

oscillates
Questão 5
Questão
The electromagnetic spectrum contains all electromagnetic waves in creation.
Responda
- True
- False
Questão 6
Questão
When light [blank_start]refracts[blank_end] into a substance in which it must slow down, the light [blank_start]ray[blank_end] will [blank_start]bend[blank_end] toward a line [blank_start]perpendicular[blank_end] to the surface it [blank_start]strikes[blank_end].
When light [blank_start]refracts[blank_end] into a [blank_start]substance[blank_end] in which it [blank_start]speeds up[blank_end], the [blank_start]light ray[blank_end] will bend away from a line [blank_start]perpendicular[blank_end] to the surface it strikes.

Questão 7
Questão
A [blank_start]diverging[blank_end] lens [blank_start]bends[blank_end] light rays outward, causing them to [blank_start]diverge[blank_end] away from one another; the [blank_start]sides[blank_end] curve outward so we say this [blank_start]lens[blank_end] has a [blank_start]convex[blank_end] shape.
A [blank_start]converging[blank_end] lens makes all [blank_start]horizontal[blank_end] light rays converge to [blank_start]a single[blank_end] point; the sides [blank_start]curve[blank_end] inward so we call this lens a [blank_start]concave[blank_end] shape.
