Mrs Pickett Waves Flashcards
What is the wave speed equation?
Wave Speed = Frequency x Wavelength
What is the units for wave speed?
Ms-1
Define Frequency
Frequency is the amount of waves that pass through a point per second
Define wavelength?
Length of a complete wave cycle
What is the order of the electromagnetic spectrum?
Radio Waves
Microwaves
Infrared
Visible Light
Ultra-Violet
X-Rays
Gamma Rays
What is a transverse wave?
A wave where it’s direction of oscillation is perpendicular to the direction of its energy transfer
What is an example of a Transverse Wave?
Electromagnetic Waves
What is a longitudinal wave?
A wave that has its oscillations parallel to the waves direction of energy transfer
What is an example of a longitudinal wave?
Sound Waves
What is reflection?
The angle of incidence is the same angle as the angle of reflection
What does i stand for?
i represents the angle of incidence
What does r represent?
r can be used to represent the angle of reflection
What is refraction?
Refraction is where light enters a different medium and it’s velocity changes. As the light arrives at the new medium at different times it causes the light to be appear bent.
What is the relationship between the angle of refraction and the speed of the wave?
The angle will increase if the wave travels faster in the new medium. But, decreases if it travels slower.
What is Total Internal Reflection?
Where light is reflected back into the medium from the boundary because the critical angle is less than the angle of incidence.
