8.33 meter is the full wavelength in air for what RF frequency? - correct answer
✅36 MHz
F=C/L
F=speed of light/wave length
F=299,792,458/8.33
Decimal 164 would appear as ___ in binary? - correct answer ✅10100100
Step 1: Divide (164)10 successively by 2 until the quotient is 0
Step 2: Read from the bottom (MSB) to top (LSB) as 10100100. This is the binary
equivalent of decimal number 164
