Q

Law of reflection

A
  • The angle of incidence is equal to the angle
  • The incident ray, the normal to the mirror at the point of incidence, and the reflected ray all lie in the same place

Q

Laws of refraction

A

1) Incident ray, refracted ray, and normal lies on the same plane

2) Denser to less dense bends away from normal

3) Less dense to denser bends toward normal

4) If the light hits the surface straight on (perpendicular), it doesn’t bend at all

Q

-thicker in the middle; are called converging lenses because they bend (refract) parallel light rays toward each other, meeting at a single point
called the principal focus (F)

front of lens

A

Principal focus

24
Q

behind the lenses

A

Secondary focus

25
Q

the line joining the optical center and principal focus

A

Principal axis

26
Q

– evolves from a latin word/term (camera obscura) meaning dark chamber

A

Camera

27
Q

– produces virtual, upright, and enlarge image of an object

A

Magnifying glass

28
Q

makes small objects bigger and is invented by father
and son team of Hans and Zacharias Janssen in 1950

A

Compound microscope

29
Q

use to differentiate cellular structures and introduced by Camillo Sebastian Nachet

A

Polarizing microscope

30
Q

to study cellular compounds like proteins and nucleic acids

A

Ultraviolet microscope

31
Q

uses electron beam instead of ordinary light and to
examine size, shape, and arrangement

A

Electron microscope

32
Q

– to see distant object appear bigger

A

Telescope

33
Q

– first type of telescope and uses refract lens

A

Refracting telescope

34
Q

– uses concave mirrors

A

Reflecting type

35
Q

Properties of telescope

A
  • How well it collects light
  • How much it magnify
36
Q

Uses to gather light

A

Aperture

37
Q

To enlarge image

A

Magnification

38
Q

– two refracting telescope mounted side by side
– pair prism
– “zoom lens” essentially a telescope mounted on camera

A

Binocular telescope

39
Q

– vector fields that are used to determine the distribution of magnetic force in areas
inside or outside

A

Magnetic field

40
Q

– manifest interrelation between magnetism and electricity

A

Electromagnet

41
Q

– phenomenon in which electric current is generated by varying magnetic field
– Changing magnetic field produces an electric current

A

Electromagnetic Induction

42
Q

– The force between the velocity and magnetic field are acting perpendicularly, the right-
hand rule is used to determine the right direction of magnetic force

A

Right hand rule

43
Q

– change in magnetic flux, induces a current (hence induced emf)

A

Faraday’s law

44
Q

– paved the way for generating electricity, through the process known as
electromagnetic induction

A

Michael faraday

45
Q

– proportional to the rate of change of the magnetic flux.

A

Induced EMF

46
Q

– the strength of a magnetic field measured in terms of the number of lines of force

A

Magnetic flux

47
Q

– the flux per unit area of a loop of wire perpendicular to the field.

A

Magnetic field

48
Q

– polarity of an induced EMF is such that it tends to produce a current which opposes
the change in the magnetic flux

A

Lenz Law

49
Q

converts electrical energy to mechanical energy

A

Motors

50
Q

converts mechanical energy into electrical energy

A

Generators
