The physics of waves This is the second in the series: ‘Seven Scientific Theories’. Imagine you have been asked to provide one or two creative and inspirational illustrations for a textbook on the physics of waves. A Marshall stack turned up to 11 (sound waves)? The colours in a film of oil (light waves)? A rainbow (the wave theory of light)? The destruction of an earthquake (primary, secondary and surface waves)? Ripples as a stone falls into a pond? The collision of two black holes generating gravitational waves? (Ocean waves breaking will be disqualified.) (The whole series is here: https://www.dpreview.com/forums/thread/4236850 )
Starts: Tuesday, 23 Jan 2018
Processing rules: No restrictions. If you don't do much Photoshop, that's fine, but please don't mark down those who do, as a principle. Small, unobtrusive watermarks are allowed, and should not be penalised in voting. Recommended image size is Facebook standard; 2048 pixels on the long side, but the challenge host (and voters) will tolerate other sizes.
Capture date rule: No restrictions
Additional rules: You must be the author of the image you enter. If you enter, please vote. If you vote, please vote fairly. The challenge host will decide whether the entry matches the brief and may disqualify any that seem not to. Please don't enter an image that has been entered into another challenge recently, or several times before. The challenge host may disqualify such entries at their discretion. Put a piece of your own soul into your entry; a simple record of someone else's art is unlikely to attract a high score. You may enter two (2) images. Photographs of ocean waves breaking will be disqualified. Be more creative and inspirational than that! Constructive comments welcomed - on any entry - at any time after the challenge has opened for submissions.
