Two microwave frequencies are authorized for use in microwave ovens, 890 and 2565 MHz. Calculate the wavelength (in cm) of each. .

337 Incorrect: Your answer is incorrect. cm (frequency = 890 MHz)

 

.116 Incorrect: Your answer is incorrect. cm (frequency = 2565 MHz)

 

(b) Which frequency (in MHz) would produce smaller hot spots in foods due to interference effects?

2565 Correct: Your answer is correct. MHz †

(a) Two microwave frequencies are authorized for use in microwave ovens, 890 and \( 2565 \mathrm{MHz} \). Calculate the wavelength (in cm) of each. * \( \mathrm{cm} \) (frequency \( =890 \mathrm{MHz} \) ) × \( \mathrm{cm} \) (frequency \( =2565 \mathrm{MHz} \) ) (b) Which frequency (in MHz) would produce smaller hot spots in foods due to interference effects? \( \mathrm{MHz} \)
