the number of waves of wavelength 6000 angstrom in a path of 2 cm in vacuum are

number of wavelength= distance trversed/wavlength= .02m/(6e3*10^-19m)=3.33..e13 waves

To find the number of waves of wavelength 6000 angstroms in a path of 2 cm in vacuum, you can use the formula:

Number of Waves = Total Path Length / Wavelength

First, convert the 2 cm into angstroms to match the wavelength unit.

1 cm = 10,000 angstroms

Therefore, 2 cm = 2 x 10,000 angstroms = 20,000 angstroms.

Now plug in the values into the formula:

Number of Waves = 20,000 angstroms / 6000 angstroms

Divide 20,000 by 6000:

Number of Waves ≈ 3.33 waves

So, the number of waves of wavelength 6000 angstroms in a path of 2 cm in vacuum is approximately 3.33 waves.

how many cm in 6000 angstroms?

Then just divide into 2
