📡 Part 1: Understanding Electromagnetic Waves

1. What type of wave are electromagnetic waves?

Longitudinal waves

Transverse waves

Surface waves

Standing waves

2. Which statement is TRUE about electromagnetic waves?

They require a medium to travel through

They can travel through a vacuum

They only travel through solids

They cannot carry energy

3. The speed of electromagnetic waves in a vacuum is approximately:

3 × 10⁶ m/s

3 × 10⁸ m/s

3 × 10¹⁰ m/s

It varies depending on the type of wave

4. Fill in the wave equation: v = _____ × _____

Where v = velocity, and the two missing variables are _____________ and _____________.

🌈 Part 2: The Electromagnetic Spectrum

5. List the seven types of electromagnetic waves in order from longest wavelength to shortest wavelength:

6. Match each electromagnetic wave type with its common application:

Radio waves

Microwaves

Infrared

Visible light

X-rays

Medical imaging

Cooking food

Vision and photography

Heat detection

Communication and broadcasting

7. Which type of electromagnetic wave has the highest frequency?

Radio waves

Visible light

X-rays

Gamma rays

🔬 Part 3: Real-World Applications

8. Explain why understanding electromagnetic waves is important for scientists and engineers. Give at least two specific examples.

9. A radio station broadcasts at a frequency of 101.5 MHz (101.5 × 10⁶ Hz). Using the wave equation v = f × λ, calculate the wavelength of these radio waves. Show your work below:

10. Choose one type of electromagnetic wave and describe both a beneficial use and a potential danger associated with it:

Wave type: _________________

Beneficial use: __________________________________________________

Potential danger: _______________________________________________
