A longitudinal wave A transverse wave Not a wave at all A dense material
Is sharp Is greater than the angle of reflection Is less than the angle of reflection Is equal to the angle of reflection
The same speed, wavelength and frequency The same speed and frequency but a different wavelength The same frequency but a different wavelength and speed The same wavelength but a different frequency and speed
By heating it By giving it a positive charge By refraction By total internal reflection
An endoscope An exoscope An electroscope A transformer
The same wavelength The same frequency A different frequency A different resistance
Slower than sound The fastest speed possible Slower than a missle Slower than a high velocity bullet
