1Why do workers in hospital x-Ray departments wear film badges?
- ATo protect them from the X-Rays
- BTo monitor their exposure to X-Rays
- CTo show where they work
2What is a CT scanner?
- AA device that uses X-Rays to produce digital images of a cross section through the body
- BUses X-Rays to produce a 2D image of the body
3Why are X-Rays not normally used to produce an image of an unborn baby?
- AX-Rays are ionising, so might harm the baby
- BWould be unable to see the whole image of the body
4The ray of light travels through glass of refractive index 1.54. The angle of incidence is 15. What is the angle of refraction?
- A12.3
- B9.7
- C10.63
5When a ray of light enters a glass block along the normal it passes without changing direction.
- AVerdadero
- BFalso
6A ray of light strikes the boundary between glass and air at the critical angle. It stays the same and doesn't refract.
- AVerdadero
- BFalso
7What is the principal focus of a diverging lens?
- AParallel Rays that pass through the lens and are refracted into a point
- BThe point that parallel rays of light appear to have diverged from after they have passed through the lens
8Describe the image formed by a diverging lens. Pick three.
- AReal
- BSmaller than the object
- CVirtual
- DUpright
- EInverted
9What are the ciliary muscles?
- AThe muscles that control the thickness of the lens in the eye
- BThe muscles that direct light into the lens
10Which type of lens may be used to correct short sight?
