Question 14:
Draw a diagram of the electromagnetic spectrum and label the regions of gamma rays, X-
rays, ultraviolet, visible light, infrared, microwaves, and radio waves.
Question 15:
A diode is connected to a battery with a voltage of 12 V. What is the current through the
diode if its forward voltage drop is 0.7 V and its resistance is 1 kΩ?
Question 16:
In the context of relativity, explain the concept of time dilation and its implications for the
measurement of time in moving frames of reference.
