MACH 1 Doppler Effect at Speed of Sound1970-01-01T00:00:00+00:00Generalised animation of a moving wave source travelling at the same speed as the waves. An example would be an aircraft travelling at the speed of sound (Mach 1). The waves expand outwards at the same speed as the object moves and concertina together ...PT13Shttps://d38zjy0x98992m.cloudfront.net/058d757c-dd5f-43fa-be82-b1ff66b8bc34/MACH_One_UHD_xlarge.jpghttps://d38zjy0x98992m.cloudfront.net/058d757c-dd5f-43fa-be82-b1ff66b8bc34/MACH_One_UHD_mp4_hd_video.mp4https://www.scientific.pictures/-/galleries/waves/-/medias/058d757c-dd5f-43fa-be82-b1ff66b8bc34/pricehttps://www.scientific.pictures/-/galleries/waves/-/medias/058d757c-dd5f-43fa-be82-b1ff66b8bc34/price
Animation of the increase in frequency observed in waves emitted from an approaching source (or conversely a decrease in frequency in waves emitted from a receding source). Happens in sound waves (e.g. a siren of an approaching emergency vehicle or the change in pitch of a passing car engine) and in light waves (the red Doppler shift of a receding star or the blue Doppler shift of an approaching star). This animation uses a ball as the wave source. As the ball moves from left to right it emits wave-fronts that continue to radiate out from their position of origin. The ball moves on and creates a new point of origin for the next wavefront and so on. In this way, the waves bunch together at the front of the ball and spread out behind. Similar to a jet plane approaching the speed of sound and radiating sound waves. In the case of light waves then the higher frequency at the front yields a bluer light (blue shift), while behind the light source (e.g. a star) the light is stretched out, lengthening the frequency, creating a redshift.

Sound Barrier1970-01-01T00:00:00+00:00Animation of a shock wave propagating from an object travelling at the speed of sound. The object compresses the air immediately in front and creates a shock wave where the waves expand outwards at the same speed as the object moves. Consequently, the ...PT6Shttps://d38zjy0x98992m.cloudfront.net/4eb59641-8698-4256-8119-2d7c90463e10/Sound_Barrier_UHD_xlarge.jpghttps://d38zjy0x98992m.cloudfront.net/4eb59641-8698-4256-8119-2d7c90463e10/Sound_Barrier_UHD_mp4_hd_video.mp4https://www.scientific.pictures/-/galleries/waves/-/medias/4eb59641-8698-4256-8119-2d7c90463e10/pricehttps://www.scientific.pictures/-/galleries/waves/-/medias/4eb59641-8698-4256-8119-2d7c90463e10/price
