optics and light

Question 1

what is reflection of light

Answer 1

Reflection light means to change the direction that light is travelling in to change the direction of light you need a reflective surface

Question 2

when a light is reflected, it follows a pattern we call this the..

Answer 2

law of reflection

Question 3

if the angle of incidence is 40 degrees the angle of reflection is

Answer 3

40 degrees ( because the angle of reflection is always the same as the angle of incidence )

Question 4

there are two types of reflection

Answer 4

Spectacular and diffuse

Question 5

specular is what type of reflection

Answer 5

specular is Refelction off a smooth surface

Question 6

diffuse is what type of reflection

Answer 6

diffuse is reflection off of rough surfaces

Question 7

what is a concave mirror

Answer 7

a mirror that is curved inwards, like a cave, is called concave

Question 8

what is a convex mirror

Answer 8

a mirror that is curved outwards, or makes a bulge, is called convex

Question 9

the single point where light rays come together is called a..

Answer 9

focal point

Question 10

in a concave mirror the image appears

Answer 10

inverted and bigger in certain angles

Question 11

where can we see the focal point for a convex

Answer 11

its not actually seen, it occurs behind the mirror we call virtual

Question 12

in a convex mirror the image appears

Answer 12

smaller and upright
