Question #3a518

Answer 1

The wavelength is 2.965 m.

Explanation:

The formula relating frequency ν and wavelength λ is

`color(blue)(bar(ul(|color(white)(a/a)νλ = c color(white)(a/a)|)))" "`

where `c =` the speed of light

From this, we get the formula for wavelength

`λ = c/ν`

∴ `λ = (2.998 × 10^8color(white)(l) "m"·color(red)(cancel(color(black)("s"^"-1"))))/(101.1 × 10^6 color(red)(cancel(color(black)("s"^"-1")))) = "2.965 m"`
