Question

1. what do scientists call wave measurement from trough to trough? a. photon b. wavelength c. amplitude d. seismic waves

Explanation:

A photon is a particle of light, not a wave measurement. Amplitude is the distance from the wave's midline to a peak or trough. Seismic waves are a type of wave, not a measurement. Wavelength is defined as the distance between two identical points on a wave, such as from trough to trough.

Answer:

B. Wavelength
