Parts of waves
This is the highest point of a wave, where the displacement of particles is at its maximum.
What is the crest?
This is the key difference between electromagnetic waves and mechanical waves in terms of their propagation medium.
What is Electromagnetic waves do not require a medium and can travel through a vacuum & Mechanical waves requires a medium?
When a wave encounters an object and bends around it.
What is diffraction?
This principle states that the frequency of a wave emitted by a source moving relative to an observer is higher as the source approaches the observer and lower as it moves away, commonly observed in sound and light waves.
What is the Doppler effect?
This type of electromagnetic waves have the shortest wavelength.
What is Gamma Rays?
This refers to the maximum displacement of a wave from its rest position, and it determines the wave's energy.
What is the amplitude?
This wave can travel through a vacuum.
what is Electromagnetic waves?
This happens to the energy of a wave as its amplitude increases.
What happens when the energy of the wave increases?
This happens when an ambulance drives past with its siren on.
What is the change in pitch caused by the movement of the ambulance
This type of electromagnetic wave has the longest wavelength.
What is Radio waves?
This is the distance between two consecutive crests or troughs in a wave.
What is the wavelength?
This type of wave moves the particles of the medium perpendicular to the direction of the wave’s propagation, such as in light or water waves.
What is a transverse wave?
This happens to the wavelength of a wave if the frequency is increased.
What is wavelength decreases?
When a police car passes by with its siren on, the sound seems to change as it approaches and then moves away. This effect happens because the sound waves are getting compressed or stretched.
What is a change in the frequency of sound due to motion?
This happens to the energy of electromagnetic waves as their wavelength decreases.
What is The energy increases?
This term describes the number of complete wave cycles that pass a given point per unit of time
What is the frequency?
These waves are characterized by the oscillation of particles in the same direction as the wave propagation, and are commonly found in sound waves.
What are longitudinal waves?
This wave behavior is light bending when it passes from air into water.
This happens to the sound of a car horn as it speeds toward you and then away from you, causing the pitch to change.
What is the change in pitch due to the car's movement?
These electromagnetic waves can be absorbed by the skin and cause sunburn.
What is Ultraviolet(UV) Rays?
These are the points where a wave has maximum downward displacement.
What is troughs?
This type of wave, often seen in water, consists of alternating crests and troughs that move energy without transporting matter.
What is a mechanical wave?
This happens when two waves meet and their effects combine to form a new wave, which can be bigger, smaller, or stay the same, depending on how the waves align.
What is wave interference?
This term refers to the apparent change in frequency or wavelength of a wave as perceived by an observer moving relative to the source of the wave, often leading to the change in pitch of a sound when the source moves toward or away from the observer.
What is the Doppler shift?
This is the difference between redshift and blueshift.
What is Red shift = object moving away (light stretched, appears red).
Blue shift = object moving toward (light compressed, appears blue)?
