Sruf these gnarley wave problems Dude
Wave Motion1. a) b)
c) d)
5λ = 35 cmλ = 7 cm
3λ = 1.7 mλ = .567 m
2λ = 11.2 ftλ = 5.6 ft
3.5λ = 54 cmλ = 15.4 cm
2. a) b) c) d)3/2λ = 3.8 mλ = 2.53 m
3 1/4λ = 41 cmλ = 12.6 cm
1/2λ = 1.8 mλ = 3.6 m
2 1/4λ = 22.5 cmλ = 10 cm
3. a) b) c)L = 4 1/2 λ = 4.5 (12 cm)L = 54 cm
L = 1 1/4 λ = 1.25 (6.7 ft)L = 8.38 ft
L = 2 3/4 λ = 2.75 (4.07 m)L = 11.2 m
4. a) λ = 2.6 m b) c)2 1/2 λ = 71.3 cmλ = 28.5 cm
3 1/2 λ = .633 ftλ = .181 ft
5. 3rd mode = 3/2 λ = L3/2(1.2m) = 1.8 m 6. 3rd mode = 3/2 λ = L
3/2(1.2m) = 1.8 m
7. 2nd mode = 3/4 λ = L = 1.8 mλ2 = 2.4 m
4th mode = 1 3/4 λ = L = 1.8 mλ4 = 1.03 m
8. 1 1/4 λ = L = 3.7 mλ3 = 2.96 m
9. 1λ = L = 2.6 m
