An electromagnetic wave has frequency of 1x10^2 Hz and a wavelength of 3x10^6m. At what speed is it traveling? someone please help I'll have brainliest and hella points I really need help and fast! ​

Trumpeter a holds a b-flat note on the trumpet for a long time. person c is running towards the trumpeter at a constant velocity. person b is running away from the trumpeter at the same rate. person d is standing still the whole time. which person hears a frequency that is lower than the b-flat?
