  1. 5

    A wave has a frequency of 11 Hz and a wavelength of 6 m. What is its speed? (v = fλ)

    λ = 6 mf = 11 Hzv = ?v = f × λ
  2. 6

    A wave travels at 496 m/s with a frequency of 31 Hz. What is its wavelength?

    λ = ?f = 31 Hzv = 496 m/sv = f × λ
  3. 7

    A wave has a frequency of 27 Hz and a wavelength of 17 m. What is its speed? (v = fλ)

    λ = 17 mf = 27 Hzv = ?v = f × λ
  4. 8

    A wave has a frequency of 48 Hz and a wavelength of 9 m. What is its speed? (v = fλ)

    λ = 9 mf = 48 Hzv = ?v = f × λ
  5. 9

    A wave travels at 221 m/s with a frequency of 17 Hz. What is its wavelength?

    λ = ?f = 17 Hzv = 221 m/sv = f × λ
  6. 10

    A wave has a frequency of 14 Hz and a wavelength of 10 m. What is its speed? (v = fλ)

    λ = 10 mf = 14 Hzv = ?v = f × λ
  7. 11

    A wave travels at 91 m/s with a frequency of 7 Hz. What is its wavelength?

    λ = ?f = 7 Hzv = 91 m/sv = f × λ
  8. 12

    A wave travels at 364 m/s with a frequency of 26 Hz. What is its wavelength?

    λ = ?f = 26 Hzv = 364 m/sv = f × λ
  9. 13

    A wave travels at 396 m/s with a frequency of 22 Hz. What is its wavelength?

    λ = ?f = 22 Hzv = 396 m/sv = f × λ
  10. 14

    A wave has a frequency of 40 Hz and a wavelength of 6 m. What is its speed? (v = fλ)

    λ = 6 mf = 40 Hzv = ?v = f × λ
  11. 15

    A wave travels at 585 m/s with a wavelength of 13 m. What is its frequency?

    λ = 13 mf = ?v = 585 m/sv = f × λ
  12. 16

    A wave travels at 240 m/s with a frequency of 48 Hz. What is its wavelength?

    λ = ?f = 48 Hzv = 240 m/sv = f × λ
