What is the difference between Qualitative Data and Quanitative Data?
Qualitative= Qualities not using numbers
Quantitative= #
When a wave bounces it is:
Reflection
Compression
Areas of a longitudinal wave where particles are closest together
What do waves transfer? What do they not
Energy not matter
The independent Variable is:
What the scientist changes in the experiment. The cause
When a wave bends entering a new medium
Refraction
Visible Light
Radiant energy is carried on this wave
Electromagnetic
The dependent variable is:
What the scientist measures or observes as a response to the independent variable
Amplitude in sound measures:
Loudness/Volume
Particles in water in an ocean wave move
in a circle (Oscillation)
Transverse
Type of wave that oscillates perpendicular to the source
A wave that requires a medium to travel
Mechanical
Define and explain the difference between Scientific Law, and Scientific Theory
Law= A consistent pattern in nature
Theory: Why things happen based on evidence
Why can't sound travel in space or a vacuum?
Sound must have atoms in order to travel, and there are no atoms in a vacuum or space.
What happens to the frequency of a wave when the amplitude is tripled?
amplitude does not affect frequency
Rarefaction is:
Area of a longitudinal wave where particles are farthest apart.
Lowest Frequency on EM Spectrum?
Radio
Difference between Replication and Repetition
Replication: scientist repeats another's experiment
Repetition: Scientist repeats their own experiment
What physical event creates all sound waves?
Vibrations
Moves energy parallel to the source
Longtitudinal
Type of wave that oscillates parallel to the direction of motion.
Longitudinal
Why does an S wave arrive second? What type of wave is it?
Transverse waves, they arrive second because they can only travel through solids.
