Hz is sound, isn't it?For q19 it's C because you need to convert it since the unit of wavelength in the table was in mm. And google "electromagnetic spectrum frequency" and you'll see that 6.34 x 10^8 Hz will correspond to microwaves
ultrasounds aren't that detailed. Lolnice job - i just checked through mine and i got same as you except for Q12 and Q19
Q12 - i thought C was more correct? - Keyhole surgery
you said B, but Ultrasound doesn't 'provide limited detail' - they're super detailed - doctors used them to see babies organs!!!
for Q19, i had A (Visible Light) ?!
