Question 1

transverse wave

Answer 1

propagates perpendicular to line of travel

frequency = Hertz -> affects wavelength, not speed

Question 2

Rule 1: The speed of wave is determined by the type of wave and medium, not the frequency

Answer 2

A higher pitch notes does not affect its speed!

Question 3

Rule 2: when a wave passes into another medium, its speed changes, but NOT its frequency

Answer 3

a rope of lighter material will have a faster velocity and faster wavelength, but same frequency

Question 4

speed of sound:

fastest in solids,

medium in liquid

slowest in gas

Answer 4

*

Question 5

greater index of refraction, the more light will bend

high frequency violet light bends MORE than red light

Answer 5

*

Question 6

Mirrors

Answer 6

1/o + 1/i = 1/f

for mirror, human is on SAME SIDE as object

o is always positive; the distance of object from mirror

i = image distance from mirror

focal length = 0.5 radius of curvature
concave -> f is positive (LEFT SIDE IS POSITIVE)
convex -> f is negative (RIGHT SIDE IS NEGATIVE)

f is focal length of mirror

positive i: image is in front of mirror and REAL/inverted
negative i: image is BEHIND mirror and virtual/upright

m is negative = inverted image
m is positive = upright image

Question 7

Mirrors

Answer 7

1/o + 1/i = 1/f

for mirror, human is on SAME SIDE as object

o is always positive; the distance of object from mirror

i = image distance from mirror

focal length = 0.5 radius of curvature
concave -> f is positive (LEFT SIDE IS POSITIVE)
convex -> f is negative (RIGHT SIDE IS NEGATIVE)

f is focal length of mirror

positive i: image is in front of mirror and REAL/inverted
negative i: image is BEHIND mirror and virtual/upright

m is negative = inverted image
m is positive = upright image

Question 8

Power = 1 / focal length (meters)

measured in diopters

P = P1 + P2

Answer 8

sdsd

Question 9

emission spectrum

Answer 9

element GAS is heated or CURRENT passed through, GLOWS a specific color, that color passed through prism, dispersion separates in component colors, corresponding to FREQUENCIES and wavelengths

PATTERN of distinct bright lines is the ES

Question 10

pauli exclusion principle

Answer 10

each atomic orbital can only hold two electrons of opposite spin

Question 11

pauli exclusion principle

Answer 11

each atomic orbital can only hold two electrons of opposite spin
