1.	The transmitting crystal emits 40° divergent beam so that the beam covers an area of approximately _____ cm diameter.(a) 10(b) 20(c) 30(d) 40I had been asked this question in an interview for job.This question is from Oximeters topic in division Oximeters of Biomedical Instrumentation
Answer» Correct option is (a) 10 The explanation is: An alternative arrangement is the array transducer which has one transmitter and six peripheral ceramic receiving CRYSTALS. The transmitting CRYSTAL emits a 40° divergent beam so that at 10 cm from the skin surface the beam covers an area of APPROXIMATELY 10 cm diameter.
