Question

are these answers correct?

7/30/20 Lab-Assignment 20 Wave Speed Discussion Wave speed is how fast distance is propagated through. Frequency is how fast cycles are completed Wave speed is calculated as the space propagated through divided by time. Questions The number of cycles completed in a given space during a given time interval increases. Circle the correct answer below. [1] The wave speed increases / decreases / stays the same. The time in which the same number of cycles is completed in a given space increases. Circle the correct answer below. (2) The wave speed increases / decreases / stays the same. The space in which the same number of cycles is completed during a given time interval increases, Circle the correct answer below. then the pe Lomme? 13] The wave speed increases / decreases stays the same. 08 The frequency of a wave increases. Circle the correct answers below. 14] The wave speed increases / decreases stays the same ] For a given time interval, there is an increase in cycles completel / space propagated through / both cycles completed and space propagated through

Answer 1

1. Wawe v=nl V = wave speed, n = no of cycles and length 'n' increases, then i've also increases The wave speed increase deoseases/ stays seme 22 When 'n' is same in given time, then we will be same. The wave speed incdeases / decreases I stays the same The wave speed increases / decreases) stays the same 4. Frequency increases, then, ware speed increases, The wave speed increasesy decreases / stays the same 5. For a given time interval, there is an increase in (cycles completed) space propagated through / both cycles cs completed and space propagated through.

6. For a given time interval, there is an increase is Eyeles cles completed space propagated / both givon cycles completed and space propagated. --- 7. Nave speed, va 6000 m 45 3 6000 10 Vnm 4 x 106 NS 1.5 mm ك۳/v The ware speed of the sound is, 24 mm/us, Jo5 Km/ms, 24 km/s 1. 5 mm/NS 8. wave speed, v= 16 mm/ps 16 X16 m = 16,000 m/s 10-6 s Space must have been in Is is 16000 m and 55 is 16,000x5 80,000m. the space must have been 4.000m; the time must have been 55, the time must have been Is, the space must have been 64 800 m Both information alion is wrong. 9. distance travel by wave is wave is a = ware speed x time 3 mm X 2 ms aps 3 x103 x2x102 10-6 s i.
