To solve this problem we will apply the concepts related to the double slit-experiment. Under this concept we understand the relationship between the minimum angle, depending on the order of the fringes, the wavelength and the distance between slits. Therefore we have the following relation,

Here,
m = Order of the fringes
D = Distance between slits
= Wavelength
Replacing with our values we have,


Through the relationship between distances then we have that the basic amplification distance is given by the relationship between the distance of the slit L and the angle, then



Thus the width of the central maximum is


Therefore the widht is 0.466m
Answer:
.
Explanation:
Sound waves are caused by vibration ripples in water are caused by disturbance in the molecules
Answer:

Explanation:
Given data
Average intensity of sunlight on one day I=700 W/m²
Power P=170 W
To find
Area A
Solution
As we know that:

A) Wavelength is the distance between two successful crests or troughs in a transverse wave or the distance between two successful compressions or rarefactions in a longitudinal wave. if the wavelength of a wave is long then the wave will diffracts more compared to a wave with a shorter wavelength because the size of the wavelength is proportional to the angle of diffraction. Such that if the gap is larger than the wavelength then the wave passes through the gap and does not spread much on the other side, while when the gap size is equal to the wavelength, maximum diffraction occurs and the waves spread greatly out.
b) Diffraction is a phenomenon that occurs when a wave encounters an obstacles or a slit. It is referred to as the bending of light around corners of an obstacles or aperture into the region of geometrical shadow of the obstacle. It is caused by one wave of light is shifted by the diffracting object which will in turn cause the wave to have interference with itself. (either constructive or destructive)
Answer:
Acceleration is the rate of change of velocity. If an object is changing its velocity, its speed, or changing its direction, then it is said to be accelerating.
Explanation:
when you change directions or speed up you are accelerating (or decelerating) and when you change directions or speed its called velocity.
