Question

a packet of electromagnetic energy is called _____ and the distance between two consecutive peaks in a wave is called ___________. 1) amplitude, frequency 2) amplitude, wavelength 3) photon, wavelength 4) wavelength, frequency

Explanation:

To solve this, we recall key physics (Natural Science - Physics) concepts:

• A photon is a packet of electromagnetic energy.
• Wavelength is the distance between two consecutive peaks (or troughs) in a wave.
• Amplitude is the height of a wave, frequency is the number of waves per unit time. So we match the terms: first blank is "Photon", second is "Wavelength", which corresponds to option 3.

Answer:

1. Photon, Wavelength
