Juliana and Asha were using a trumpet to test how sound waves travel. Juliana blew a series of notes through the trumpet, while Asha changed her location around the room in between each trial. Asha found that the horn sounded loudest when she was in a direct line from where the sound originated. What is the term for this type of wave? A. latitudinal B. longitudinal C. compressed D. diffracted

To determine the correct term for the type of wave described in the scenario, let's analyze the information provided:

1. Juliana blew a series of notes through the trumpet, producing sound waves.
2. Asha found that the horn sounded loudest when she was in a direct line from where the sound originated.

Sound waves are a type of mechanical wave that travels through a medium (such as air) by causing the particles of the medium to vibrate. The key detail here is that the sound was loudest when Asha was in a direct line from the source, indicating that the wave travels in the same direction as the vibration of the particles.

Let's evaluate the options:

A. Latitudinal: This term is not commonly used to describe sound waves. B. Longitudinal: This term describes waves where the particle displacement is parallel to the direction of wave propagation. Sound waves in air are longitudinal waves. C. Compressed: This term refers to the regions of high pressure in a longitudinal wave but is not the term for the type of wave itself. D. Diffracted: This term describes the bending of waves around obstacles, not the type of wave.

The correct term for the type of wave described is:

B. longitudinal
