| 2883706141 | Radio waves; long wavelength or low frequency has low or high energy? | Low energy | 0 | |
| 2883707733 | Gamma rays; short wavelength or high frequency has low or high energy? | High energy | 1 | |
| 2883717456 | The visible spectrum of light is what wavelength | 380-760 nm | 2 | |
| 2883730689 | Electromagnetic are what types of waves and why? | Transverse waves because the oscillating electric and magnetic field vectors are perpendicular to the direction of propagation | 3 | |
| 2883748769 | What equation is used to determine the wavelength or frequency of light traveling in air or vacuum? | m/s=c (3x10^8 m/s) Vis f=s-1 Lambda= m |  | 4 |
| 2883770370 | Wavelength of the radio | 10^9m-1m | 5 | |
| 2883771856 | Wavelength of the microwave | 1m-1mm | 6 | |
| 2883777925 | Wavelength of IR | 1mm-700nm | 7 | |
| 2883816071 | Wavelength of visible light | 700 nm-400 nm ROY G BIV (recall the colour order) | 8 | |
| 2883819536 | Wavelength of UV | 400nm-50nm | 9 | |
| 2883822075 | Wavelength of x-ray | 50nm-10^-2 nm | 10 | |
| 2883823432 | Wavelength of gamma rays | 10^-2 or less | 11 | |
| 2883836847 | Visible light (Violet Wavelength) | 380 nm | 12 | |
| 2883841016 | Visible light (Red Wavelength) | 760 nm | 13 | |
| 2883846941 | Blackbody | Is used to describe an ideal radiator, refers to the fact that such an object is also an ideal absorber and would appear totally black if it were at a lower temperature than its surroundings | 14 | |
| 2883875515 | What is rectilinear propagation? | When light travels through a single homogenous medium, it travels in a straight line | 15 | |
| 2883880164 | Geometrical Optics | The behaviour of light at the boundary of a medium or interface b/w two media -> Pertains to the behaviour of reflection and refraction, as well as the study of mirrors and lenses | 16 | |
| 2883904198 | What is reflection? | Reflection is the rebounding of incident light waves at the boundary of a medium. Light waves are not absorbed into the second medium; rather they bounce off of the boundary and travel back to the first medium | 17 | |
| 2883915475 | What is law of reflection? |  | 18 | |
| 2883922399 | Reflection in a plane mirror | In general, images created by a mirror can be either real or virtual. An image is said to be *real* if the light actually actually converges at the position of the image. An image is *virtual* if the light only appears to be coming from the position of the image but does not actually converge there |  | 19 |
| 2883951799 | Spherical Mirrors | Come in two varieties, *concave and convex* -> Spherical mirrors have a *centre of curvature (C)* and a *radius of curvature (r)* -*Centre of curvature*- where the centre of the mirrored sphere would be, were it a complete sphere |  | 20 |
| 2883992216 | Mirror Equation | f= focal length, is the distance b/w the focal point (F) and the mirror o= the distance of the object from the mirror i= the distance of the image from the mirror |  | 21 |
| 2884021393 | The mirror picture of a concave with variables |  | 22 |
