Science Revision - Waves
Cards in this deck (25)
- 1What is a wave?A vibration that transfers energy from one location to another.
- 2What is a longitudinal wave?Has vibrations parallel to the direction the energy is moving in
- 3What is a transverse wave?Vibrations perpendicular to the direction energy is moving in.
- 4How are sound waves producedVibrations of particles
- 5What type of wave is sound?Longitudinal wave
- 6Where does sound travel fastest?In solids as the particles are closes together
- 7What is the amplitude?The height of the wave crest
- 8What is the wavelength?Distance from one wave crest to another
- 9What does increasing the amplitude do?Increases the loudness of a sound
- 10What does increasing the frequency do?Increases the pitch of waves
- 11How is energy transferred to our eyes?Light waves
- 12What are shadows?Result of light travelling in straight lines
- 13What is the normal?imaginary line at a right angle to the mirror
- 14What is the incident ray?ray incoming to the mirror
- 15What is the reflected ray?Ray that bounces back from the mirror
- 16What is the angle of incidence?Angle between the incidence ray and the normal
- 17What is the angle of reflection?Angle between the reflected ray and the normal
- 18What is the law of reflection?Angle of incidence is equal to angle of reflection
- 19What causes reflection?Mirrors by reflecting light at the same angle that lights hits it
- 20What is refraction?Refraction is when light changes direction when it enters a different medium
- 21Why does refraction happen?Because the density of water is stronger
- 22How do rainbows form?When light passes through a prism and is refracted
- 23How do you cancel out refraction?By using 2 prisms
- 24What is the longest wavelength?Red - it has been dispersed the least
- 25What is the shortest wavelength?Violet, it has refracted the most
