Hi Maria !

Physics Wave Question

31 Diagram 21 shows the position of a shooter and a concrete wall when the shooter shoots. Rajah 21 menunjukkan kedudukan penembak dan dinding konkrit apabila penembak melepaskan tembakan.

Diagram 21/ Rajah 2l
What is the time interval between the shooting sound and its echo heard by the shooter? [T h e s p e e d of the ~ s o u n d ~ i n ~ a i r ~ i s ~ 330 \mathrm{~ms}^{-1} ]
Apakah sela masa Antara bunyi tembakan dengan gemanya yang didengari oleh penembak?[ Halaju bunyi di udara ialah 330 \mathrm{~ms}^{-1} |
A \quad 0.0 \mathrm{~s}
C \quad 1.0 \mathrm{~s}
B. 0.5 \mathrm{~s}
D. \quad 2.0 \mathrm{~s}

Physics Wave Solution

To solve this question we must use this formula:


d= distance travelled / depth
v = wave speed
t = time interval

From the question:

d= 330m
v= 330ms-¹
t = ?



Oh god thank you so much I finally understand :star_struck::star_struck:
