waves + evolution

how is energy transfered

oscilaltions/vibrations

how do longitudinal waves travel

particles vibrate parallel to the direction that the wave is travelling

how do transversal waves travel

particles vibrate 90 degrees to the direction that the wave is travelling

example of longitudinal wave

sound wave

Examples of transverse waves

water wave

how to measure amplitude

height from normal to either peak or trough

do mechanical waves need matter to travel

yes

do electromagnetic waves need matter to travel

no

what are p waves

earthquake waves

what can p waves travel through

rock and solid

what can s waves travel through

only solids

em spectrum

Raging Martians Invaded Venus Using X-ray Guns

does longer wave length result in more or less energy

less energy

when a wave has less energy how does that impact its frequency?

less frequent

what is refraction

bending of wave (light, sound, water) when it passes at an angle from one transparent or translucent medium into another

what is scattering

when light rays hit tiny pieces of matter (such as dust, gas, or water drops) and bounce off in many directions instead of going in a straight liine

law of reflection

angle of incidence = angle of reflection

during refraction, what happens when light enters denser medium

slows down

during refraction, what happens when light enters a less dense medium

speeds up

what is genotype

genetic makeup of organisms

what is phenotype

physical expression of genes

what is TT

homozygus dominant

what is Tt

heterozygous

what is tt

homozygous recessive

in pedigree diagram, what does circle represent?

girl

in pedigree diagram, what does a square represent

male

in pedigree diagram, what does a shaded shape represent

the trait that is being tracked

in pedigree diagram, what do the roman numerals mean

the generations

what are the evidences of evolution

fossils, comparative anatomy, dna similarities

what is lamarck theory

used/acquired characteristics go to offspring = change because aquired characteristics are inherited

what is darwin theory

natural selection = evolve over gens

what is speciation

when a new species is formed
