Explanation:
The wavelength of light λ=687 nm.
width of the slit, w=0.75 mm.
The diffraction formula for single slit diffraction is;
m here is an integer.
For small θ, sinθ≅ θ.
The formula changes to;
.
The data in the question is missing. However, one put data in the above formula to find the unknown.
Answer:
The object with the smallest mass.
Explanation:
According to Newton's 2nd law:
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. In other words Acceleration=Force/mass; The smaller the mass, the greater the acceleration. The object with the smallest mass will have the largest acceleration.
The speed of a 16cm wave with a period of 8 seconds is 2cm/s
<h3>How to determine the speed</h3>
Using the formula;
Speed = distance ÷ time
Distance = 16cm
time = 8 seconds
Substitute into the formula
Speed = 16 ÷ 8
Speed = 2 cm/s
Therefore, the speed of a 16cm wave with a period of 8 seconds is 2cm/s
