1What speed does light travel at?
- A3 x10,8 m/s
- B30 x10,8 m/s
- C2 x10,8 m/s
- D3 x10,7 m/s
2All electromagnetic waves travel at the same speed.
- AVerdadeiro
- BFalso
3Micro-waves have a shorter wave-length than gamma rays
- AVerdadeiro
- BFalso
4All the waves in the electromagnetic spectrum have different [blank_start]frequencies[blank_end] and [blank_start]wavelengths[blank_end] but they al travel at the same [blank_start]speed[blank_end] 3 x10,8 m/s.
- Afrequencies
- Bwavelengths
- Cspeed
5The height of a wave from the zero position is known as?
- AThe crest
- BThe trough
- CThe amplitude
- DThe wavelength
6To measure wavelength you require the frequency of the wave and the speed the wave is travelling at.
- AVerdadeiro
- BFalso
7When light moves from one medium into another it changes [blank_start]speed[blank_end]. This is known as [blank_start]refraction[blank_end]. This process can lead to some interesting effects such as change in [blank_start]direction[blank_end] when the light passes through one material into another.
- Aspeed
- Bdirection
- Crefraction
- Dreflection
- Edirection
- Fbrightness
8The angle of incidence equals the angle of reflection
- AVerdadeiro
- BFalso
9A [blank_start]higher pitched[blank_end] sound will contain more waves than a [blank_start]lower pitched[blank_end] sound, and a [blank_start]quiet[blank_end] sound will have a smaller [blank_start]amplitude[blank_end] than a louder sound.
- Ahigher pitched
- Blower pitched
- Cquiet
- Damplitude
10Convex lenses cause parallel rays of light to . . .
- AConverge (come together)
- BDiverge (spread out)
11Concave lenses cause parallel rays of light to . . .
- ADiverge (spread out)
- BConverge (come together)
