Q

What are theories?

A

Once enough observations and laws fall to place these observations and laws become a theory, a theory provides a general explanation for observations in his created to explain these observations

Q

The ratio of speed of light and a vacuum to speed in a given material is called the

A

Index of fraction

17
Q

When light passes from one transparent medium into another with a different index of refraction part of it, incident light is reflected at the boundary. The remainder passes into the new media of the ray of light is incident at an angle that is not perpendicular the ray change the direction or _____ as it enters the new medium

A

refracts

18
Q

The angle of a fraction depends on the speed of light in the two media, and on the incident angle. a mathematical relationship exist between this quantities known as

A

Snells law

19
Q

The photo electric effect is the ejection of what from the surface of metal by light

A

Electrons

20
Q

The particle theory of matter is an example of what?

A

A robust theory

21
Q

What scientist attempted to measure the speed of light by measuring the time it took for light to travel unknown distance between two hilltops

A

Galileo

22
Q

What scientist who is a Danish astronomer who made the first quantitive measurements of the speed of light by studying Jupiter’s moon

A

Roemer

23
Q

What scientist express the speed of light as 16 2/3 earth diameters per second

A

Huygens

24
Q

What scientist shone a light between the teeth of a rapidly rotating tooth wheel apparatus with a distant mirror

A

Fizeau

25
Q

A French physicist who used a pendulum device to demonstrate the effect of the earth rotations on the speed of light

A

Foucault

26
Q

An American scientist to improved on the work of earlier scientist by using an eight sided rotating mirror to calculate the speed of light

A

Michelson

27
Q

What was Hugen’s principle?

A

States that every point on a wavefront can be considered as a point source of tiny secondary wavelets that spread out in front of the wave at the same speed as the wave itself. The surface envelope tangent to all the way, but constitutes a new wave front

28
Q

Light travels in a straight line

A
