Thunder vs. Lightning: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 12, 2023
Thunder is the sound produced by the rapid expansion of air along a lightning strike. Lightning is a visible electrical discharge between clouds or from cloud to ground, often causing thunder.
Key Differences
Thunder is a sound that originates from the rapid heating and expansion of air surrounding a lightning bolt. Lightning, on the other hand, represents the visible discharge of electrical energy. Both are intrinsic parts of a thunderstorm, but one appeals to our sense of hearing and the other to our sense of sight.
Thunder cannot exist without lightning, as it is the energy from the lightning that causes the air to heat and produce the thunderous sound. Lightning, however, can exist without thunder being perceived, especially when it occurs very far from a listener, showcasing that the physical phenomenon and our perception of it can be detached.
Thunder always follows lightning, due to the speed of light being much faster than the speed of sound. This means we see lightning before we hear the associated thunder. Lightning provides a direct and immediate visual of its occurrence, whereas thunder provides a delayed auditory experience.
Thunder varies in its auditory expression; it may rumble softly or crack loudly, depending on the distance and nature of the lightning. Conversely, lightning may appear as jagged bolts across the sky or simply illuminate clouds from within, showcasing variability in visual presentations.
