Answer:
width of fringes are increased
Explanation:
The width of central maxima is given by the following expression
Width = 2 x Dλ / d
- D is distance of screen from source , d is slit width and λ is wavelength of light source.
- Here we see , on d getting decreased , width will increase because d is in denominator .
Due to increased width , position of a fringe moves away from the centre.
The 'Rite of Spring' was composed by Igor Stravinsky.
The correct answer to the question is : C) Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
EXPLANATION :
Before going to answer this question, first we have to understand speed and acceleration.
The speed of a body is defined as the rate of change of distance or the distance covered by the body per unit time. Speed is scalar quantity. Hence, it needs only magnitude for its complete specification.
The acceleration produced by a body is defined as the rate of change of velocity. We know that velocity is the speed in a particular direction. Hence, the acceleration is not only produced due to the change in magnitude of velocity as well as due to the change in direction. Hence, acceleration is a vector quantity which needs magnitude as well as direction for its complete specification.
Hence, the best difference between speed and acceleration is the third statement.
