Two different sets of #IridescentVapourTrails captured from Oxfordshire, UK 15 June '25 The colours are created when sunlight is diffracted by tiny water droplets that condense out over the aircraft wings. Canon 1100D + 300mm zoom lens #AtmosphericOptics #Aviation #Diffraction

747 with long vapour trails that are displaying a spectrum of pastel colours. This effect is caused by diffraction of sunlight through tiny water droplets that that condensed out over the wings and when the Sun passes through them at the right angle the component colours of sunlight are split and a colour dispersion is seen
