An air-filled cavity for producing electromagnetic standing waves has two parallel, highly conducting walls separated by a distance L. One standing-wave pattern in the cavity produces nodal planes of the electric field with a spacing of 1.50 cm. The next- higher-frequency standing wave in the cavity produces nodal planes with a spacing of 1.25 cm. What is the distance L between the walls of the cavity?

Question

Transcribed Image Text:An air-filled cavity for producing
electromagnetic standing waves has two
parallel, highly conducting walls separated by
a distance L. One standing-wave pattern in the
cavity produces nodal planes of the electric
field with a spacing of 1.50 cm. The next-
higher-frequency standing wave in the cavity
produces nodal planes with a spacing of 1.25
cm. What is the distance L between the walls
of the cavity?
