The microwaves in a certain microwave oven have a wavelength of 12.2 cm.

Part A

How wide must this oven be so that it will contain five antinodal planes of the electric field along its width in the standing wave pattern?

L = cm

Part B

What is the frequency of these microwaves?

f = Hz
Part C

Suppose a manufacturing error occurred and the oven was made 6.0cm longer than specified in part (a). In this case, what would have to be the frequency of the microwaves for there still to be five antinodal planes of the electric field along the width of the oven?

f = Hz

Asubject in a clinical research trial experiences a serious, unanticipated adverse drug experience. how should the investigator proceed, with respect to the irb, after the discovery of the adverse event occurrence? a. do not report the adverse drug experience to the irb since it is a common adverse experience.b. report the adverse drug experience to the irb only if there are several other occurrences.c. report the adverse drug experience as part of the continuing review report.d. report the adverse drug experience in a timely manner, in keeping with the irb's policies and procedures, using the forms or the mechanism provided by the irb.
