1V[blank_start]isible[blank_end] light can be dispersed into a spectrum using a p[blank_start]rism[blank_end]
- Aisible
- Brism
2Violet light has a longer wavelength than red light
- AVerdadero
- BFalso
3There are three types of ultraviolet waves, known as UV-[blank_start]A[blank_end], UV-B and UV-[blank_start]C[blank_end]. UV-[blank_start]C[blank_end] waves can cause the most damage because they have the [blank_start]shortest[blank_end] wavelength
- AA
- Bshortest
- CC
- DC
4Infrared was discovered while experimenting with silver chloride used in photography
- AVerdadero
- BFalso
5Label the electromagnetic spectrum
- Aradio
- Bmicrowaves
- Cinfrared
- Dvisible light
- Eultraviolet
- Fx-rays
- Ggamma-rays
6Electromagnetic waves consist of an [blank_start]oscillating[blank_end] electric field combined with an oscillating [blank_start]magnetic[blank_end] field. The two fields are at [blank_start]right[blank_end] angles to each other and to the direction of travel, so EM waves are [blank_start]transverse[blank_end].
- Aoscillating
- Bmagnetic
- Cright
- D45 degree
- Etransverse
- Flongitudinal
7Microwaves are very high frequency and short wavelength radio waves
- AVerdadero
- BFalso
8M[blank_start]edium[blank_end]-frequency waves can reflect off the i[blank_start]onosphere[blank_end] to communicate long distances. These reflected waves are called s[blank_start]ky[blank_end] waves. Space waves are high frequency radio waves that travel in straight lines to s[blank_start]atellites[blank_end] in space. M[blank_start]obile[blank_end]-phone networks use these to communicate around the world at high speeds.
- Aedium
- Bonosphere
- Cky
- Datellites
- Eobile
9[blank_start]Infrared waves[blank_end] are used in cooking, in the grill and in toasters.
[blank_start]Visible light[blank_end] is sued to light our homes and in photography.
Rescue services use [blank_start]infrared[blank_end] cameras to find bodies under rubble.
Some security markings can only be seen under [blank_start]ultraviolet[blank_end] light, such as the markings on bank notes.
[blank_start]Ultraviolet[blank_end] light is also used to sterilise water, as it kills bacteria.- AInfrared waves
- BUltraviolet waves
- CX-rays
- DVisible light
- EInfrared light
- Finfrared
- Gvisible light
- Hultraviolet
- Imicroscopic
- JUltraviolet
- KStrong visible
10Photographs taken with infrared are called t[blank_start]hermographs[blank_end].
- Ahermographs
11Both visible light and infrared waves can be transmitted along optical fibres for communication
- AVerdadero
- BFalso
12T[blank_start]otal[blank_end] i[blank_start]nternal[blank_end] r[blank_start]eflection[blank_end] is a phenomenon where 100% of the light is reflected back into a material, when the ray hiots the glass/air boundary at an angle that is greater than the critical angle
- Aotal
- Bnternal
- Ceflection
13What can x-rays be used for?
- Aairport security scanners
- Bmedical x-rays to detect condition of bones and teeth
- Cto detect unwanted metal in machinery
- Dto cook
- Eto find bodies under rubble
14What type of wave can cause permanent damage to the retina? (as the most damage it can cause?)
- Amicrowaves
- Bx-rays
- Cinfrared
- Dvisible light
15What type of wave can cause eye conditions, such as cataracts? (most damage it can cause?)
- Aultraviolet
- Bx-rays
- Cinfrared
- Dgamma
16Ionisation is when electrons get knocked off an atom when passing through materials to form a negative ion
- AVerdadero
- BFalso
17When an [blank_start]alpha[blank_end] or beta particle enters the [blank_start]Geiger-Muller[blank_end] tube, it ionises the gas inside the tube. This produces a pulse of [blank_start]electrical[blank_end] charge, with each click or count representing a [blank_start]particle[blank_end] being detected.
- Aalpha
- Belectron
- CGeiger-Muller
- Delectrical
- Eparticle
- Fion
- Gradioactive substance
