Everyday Science / Branch of Science — Multiple-choice practice
لہر کی رفتار کے لیے کون سا اظہار اچھا ہے؟
- A. V=λ/f
- B. V=f/λ
- C. V=T/λ
- D. none
Correct answer
V=f/λ
Explanation
Explanation V=f/λ is an expression that holds good for wave velocity *** The wave velocity of a wave is given by v=fλ **** lambda = refers to the wavelength, the distance between the crests in meters (m) v = refers to the velocity of the speed of waves moving in a direction in meters per second (m/s) f = refers to the frequency, the wave crests that go through a point in certain time cycles per second or hertz (cycles/s or Hz) ****** RY 23-12-2022
