Question

Calculate the wavelength of light having speed 440 m/sec. and frequency is 210 Hz

Answer 1

Answer:

2.57 feet

Explanation:

Answer 2

Wavelength of light is 2.1 m

Solution

Wavelength : Wavelength is distance b/w two successive throughs of a wave.

Wavelength is given by,

✪ Wavelength = Speed/Frequency

Now we have,

Speed of light = 440 m/s

Frequency = 210 Hz

Wavelength = ?

Using the same formula :

✪ Wavelength = Speed/Frequency

⇒ Wavelength = 440/210

⇒ Wavelength = 2.1 m

So to say,

∴ Wavelength of light = 2.1 m
