Study Pack | Accurate & Verified Answers |
A+ Verified
• amplitude -✓✓maximum displacement of a point on the wave from
its undisturbed position
• Wavelength -✓✓distance between same point on two adjacent
waves
• frequency -✓✓number of complete waves passing a certain point per
second
• measurement of frequency -✓✓Hz
• transverse waves -✓✓oscillations are perpendicular to the direction
of energy transfer
• examples of transverse waves -✓✓EM waves, ripples in water, waves
on a string
• Longitudinal waves -✓✓oscillations parallel to direction of energy
transfer
,• examples of longitudinal waves -✓✓sounds waves in air, shock eaves
e.g. some seismic waves
• What is wave speed -✓✓speed at which energy is being transferred /
speed wave moving at
• wave speed formula -✓✓wave speed (m/s) = frequency (Hz) x
wavelength (m)
• How would an Oscilloscope be used to measure the speed of sound?
-✓✓
• What happens when a wave reaches a boundary between two
different materials? -✓✓absorbed by material trying to cross- wave's
energy transferred to material energy stores
transmitted- waves carry on travelling through material
reflected
• rules for ray diagram for reflection -✓✓angle of incidence= angle of
reflection
• normal -✓✓imaginary line that's perpendicular to the surface at the
point of incidence- usually dotted line
, • types of reflection -✓✓specular
diffuse
• Specular reflection -✓✓wave reflected in single direction by a
smooth surface e.g. mirror
• diffuse reflection -✓✓waves reflected by a rough surface and rays
are reflected in lots of different directions.
Happens because normal is different for each incoming ray so angle of
incidence is different for each different ray.
Surface appear matte
• EM waves -✓✓transverse waves that transfer energy from a source
to an absorber
All EM waves travel same speed through air or vacuum
form continuous spectrum over range of frequencies
• EM spectrum -✓✓Left to right- increasing frequency and decreasing
wavelength
• why is there a range of frequencies on EM spectrum? -✓✓generated
by a variety of changes in atoms and nuclei
because of different properties used for different purposes
