Answer:
Width of the frame = 54 cm
Step-by-step explanation:
- Find area of the frame = l*h = 18*12 = 216 cm
- Area of the frame = area of the photograph = 216 cm
- Use the given fact, photograph is surrounded by a frame of uniform width = all sides are equal.
- width of the frame = 216/4 = 54

T = ___________ s
Answer:

Step-by-step explanation:
Given:
Thickness og glass = L
Index of refraction n=1.5
Frequency = f

λ(air) 
λ(glass) = λ(air) / n
= 
= 
= 
V(glass) = fλ(glass)
