waves (tama na pls)

Question 1

Waves

Answer 1

Disturbance that carry energy through a medium or empty space

Question 2

Mechanical waves

Answer 2

Waves transmit energy in a particle-filled medium.

Question 3

Electromagnetic wave

Answer 3

Transmitted in empty space or vacuum

Question 4

Transverse wave

Answer 4

Particle in the medium move perpendicular to the direction of the wave

Question 5

Longitudinal wave

Answer 5

Particles in the medium move parallel to the direction of the wave

Question 6

Surface wave

Answer 6

Combination of transverse and longitudinal

Question 7

Compression

Answer 7

area where particles are close to one another

Question 8

Rarefaction

Answer 8

area where the particles are far from one another

Question 9

Crest

Answer 9

High point of a wave

Question 10

Trough

Answer 10

Low point of a wave

Question 11

Wavelength

Answer 11

Distance between two successive crest or troughs

Question 12

Frequency

Answer 12

number of complete waves passing a given point every second

Question 13

Period

Answer 13

number of seconds it takes for one complete wave to pass through a single point

Question 14

Wave speed formulas

Answer 14

V= λF or V= λ/T

Question 15

Reflection

Answer 15

occurs when waves bounce back after striking a barrier

Question 16

Refraction

Answer 16

waves bend due to the change in their velocity

Question 17

Diffraction

Answer 17

property of waves travel around its end

Question 18

Interference

Answer 18

two waves interact as they pass through a single medium at the same time

Question 19

Constructive Interference

Answer 19

crest + crest / troughs + troughs = greater pulse

Question 20

Destructive Interference

Answer 20

Crest + Troughs = lower pulse

Question 21

Standing waves

Answer 21

reflected waves have the same amplitude, frequency, and speed as the original wave

Node

Answer 22

di ko alam

Question 23

Antinode

Answer 23

midpoint daw ng destructive
