1. Why is c used as the speed of light and the speed of television waves?

They actually use the letters tv to designate the speed of television waves

All electromagnetic radiation travels at the same speed in a vacuum

Because television waves are actually visible light

2. What is the approximate frequency range of the full electromagnetic spectrum?

From 50 Hz to 10¹⁹ Hz

From 6000 km to 0.03 nm

From 4*10¹⁴ to 7.5*10¹⁴ Hz

3. Who was Roy G. Biv?

He is credited with inventing visible light

He is a fictitious cartoon character that has many colors

Those are just the letters of the visible spectrum to aid in memorizing them

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
