Exam-style question
Try this first
What is the relationship between wavelength and frequency in electromagnetic waves?.
- A.Wavelength is directly proportional to frequency.
- B.Wavelength is inversely proportional to frequency.
- C.Wavelength and frequency are independent of each other.
- D.Wavelength increases as frequency increases.
Model answer
What a good answer should say
- Wavelength is inversely proportional to frequency.
Explanation
Why this works
This is correct because the speed of light is equal to the product of wavelength and frequency (c = λf), indicating that as frequency increases, wavelength decreases, and vice versa.
