Beath High School - Int 1 Physics2 angle of incidence Angle of incidence to concave lens angle of reflection background radiation bacteria concave lens the angle between the ray of incidence and the normal the angle between the ray of reflection and the normal the radioactivity which is around us all the time tiny germs which can cause diseases a lens which is thinner in the middle than at the edges

Beath High School - Int 1 Physics3 converging converging to fibrescope convex lens diverging endoscope fibrescope making rays of light come to a focus a lens which is fatter in the middle than at the edges making rays of light spread out bundles of optical fibres used to see inside peoples’ bodies another name for an endoscope

Beath High School - Int 1 Physics4 fluorescence fluorescence to laser gamma rays infrared invisible laser the glow of light from some chemicals when uv is shone on to them very penetrating waves - a type of radioactivity radiated heat cannot be seen by the human eye a special source of light, producing a very bright, narrow beam

Beath High School - Int 1 Physics5 long sight Long sight to psoriasis normal optical fibre plane mirror psoriasis seeing far objects clearly, but near objects blurred a line at right angles to a surface a long, thin, flexible piece of glass through which a beam of light can travel a flat mirror a type of skin condition

Beath High School - Int 1 Physics6 retina retina to total internal reflection short sight source thermogram total internal reflection the light sensitive layer inside the eye seeing close objects clearly, but far objects blurred something which gives out its own light a photograph taken using the heat from an object light bouncing off the inside surfaces of glass fibre
