<prompt> Fana ka mehlala e meraro ea phello ea Doppler.nan  <response>: Instruction in English: Give three examples of the Doppler effect. . Response in English: 1 Sound of a passing ambulance: As an ambulance with its siren on approaches, the wavelength of the sound waves is compressed, resulting in a higher pitch. As the ambulance passes and moves away, the wavelength of the sound waves is stretched, resulting in a lower pitch.2 Change in the pitch of a train whistle: When a train is approaching a station, the whistle sound appears to increase in pitch to observers on the platform. The whistles pitch then decreases as the train moves away from the platform.3 Redshift and blueshift of light from distant galaxies: When observing light from distant galaxies, scientists can detect a shift in the wavelength of light due to the relative motion of the galaxy and the observer. If the galaxy is moving away, the light will be shifted towards the red end of the spectrum redshift. If the galaxy is moving towards the observer, the light will be shifted towards the blue end of the spectrum blueshift. . Response in Sesotho: 1 Molumo oa ambulense e fetang: Ha ambulense e nang le siren e atamela, bolelele ba maqhubu a molumo boa hatelloa, e leng se etsang hore ho be le molumo o phahameng. Ha ambulense e feta me e tsamaea, maqhubu a molumo a a otloloha, e leng se etsang hore ho be le molumo o tlaase. 2 Ho fetoha ha molumo oa mololi oa terene: Ha terene e atamela seteisheneng, molumo oa mololi o bonahala o eketseha ho bashebelli ba sethaleng. Joale molumo oa mololi oa fokotseha ha terene e tloha sethaleng. 3 Bofubelu bo bofubelu le boputsoa ba khanya bo tsoang ho lihlopha tsa linaleli tse hōle: Ha bo-rasaense ba shebile khanya e tsoang ho lihlopha tse hōle tsa linaleli, ba ka lemoha ho fetoha ha leqhubu la khanya ka lebaka la ho tsamaea ho lekanyelitsoeng ha sehlopha sa linaleli le moshebelli. Haeba sehlopha sa linaleli se suthela hole, leseli le tla suthisetsoa pheletsong e khubelu ea mabala redshift. Haeba sehlopha sa linaleli se leba ho seshebelli, leseli le tla suthisoa ho ea pheletsong e putsoa ea mabala blueshift.
