Sound waves by Mind Map: Sound waves

1. Similarities and differences between light waves and sound waves

1.1. Similarites

1.1.1. Both sound and light waves reflect and refract

1.1.2. Both sound and light waves are wave motions and therefore have all the properties of a wave.

1.2. Differences

1.2.1. Sound waves are longitudinal waves, whereas light waves are transverse waves

2. Ultrasound

2.1. Uses of Ultrasound

2.1.1. Detection of developmental/ structural abnormalities in the fetus.
