Homework Answers
Given , λ = 300,000 km = 300,000*10^3 m = 3*10^8 m
Speed (v) = 3*10^8 m/s
Frequency (f) = v/λ = 3*10^8 /3*10^8 = 1 Hz
f = 1 Hz
Answer) option b)1 Hz

Just not getting this! Multiple Choice Strategy: Some students have suggested that if you have to guess on a multiple-choice question, you should always choose C. Carl, the student, wants to investigate this theory. He is able to get a sample of past tests and quizzes from various teachers. In this sample there are 80 multiple-choice questions with four options (A, B, C, D). The distribution of correct answers from this sample is given in the frequency table below. Correct...

This question has multiple parts
Question 8 Two waves with identical frequency f and amplitude A are superimposed on each other. The waves are partially out of phase (one is shifted by 1/4 wavelength compared to the other). The resultant wave will have: Select the correct answer O Frequency less than f, amplitude equal to 2A O Amplitude exacly equal to 0 O Frequency equal to f,amplitude less than 2A O Frequency equal to f, amplitude equal to 2A Frequency...

A TV station has a weather radar which is monitoring an
approaching thunderstorm. The radar emits radio waves at a
frequency of 2900 MHz . The thunderstorm line is approaching the
radar installation at 45.0 km/h
Radio waves are reflected from the water drops in the
thunderstorms, and the reflected waves are detected back at the
installation. As measured by the receiver at the installation, is
the frequency of these reflected waves greater or less than 2900
MHz ?
