In a stationery wave, the phase angle between a node and a consecutive antinode is:
Correct answer: A. 90 degree
- A. 90 degree
- B. 180 degreee
- C. 270 degree
- D. 150 degree
Explanation
The ange between node and antinode is 90 degree.The angle between two nodes or two antinodes (or adjacent crests and troughs) is 180 degree.The angke between two crests (or two troughs) is 360 degree.1 wavelength is equal to 360 degree.3/4 wavelength is equal to 270 degree.1/2 wavelength is equal to 180 degree1/4 wavelength is equal to 90 degree.

About Stationary Waves
Stationary waves form when two waves of the same frequency and amplitude travel in opposite directions and interfere. The topic covers nodes, antinodes, wavelength, phase, resonance, and the allowed frequencies on strings and in air columns. Unlike progressive waves, stationary waves do not transfer energy from one point to another.
