Question

Which of the following is the symbol for wavelength ?
1. Hertz
2. Lambda
3. Beta
4. Alpha

Answer 1

Correct Answer - Option 2 : Lambda

The correct answer is Lambda.

• Wavelength is defined as the property of a wave in which the distance between the identical points between the two successive waves is calculated.
• It is denoted by the Greek letter lambda (λ).
• Therefore, the distance between either one crest or trough of one wave and the next wave is known as wavelength.
• The wavelength of light is defined as “The distance between the two successive crests or troughs of the light wave”.
• The wavelength of the Visible Light ranges between 400 nm to 700 nm.

• Frequency is defined as the total number of complete cycles per unit time.
• It is denoted by “f”.
• The frequency is defined in terms of cycles/second.
• The unit of frequency is Hertz.
