Answer:
Acceleration is the rate of change in velocity.
Explanation:
For example if you were riding in a car the change in velocity which is defined as an speed in direction. So if you were in a car and the car went from 30 MPH to 40 MPH the speed of the car has accelerated giving you acceleration.

Given,
Radius of curvature of concave mirror = 1.6m
We know that ,
Focal length = radius/2
Hence ,
Focal length of concave mirror = radius of concave mirror /2
=> F = 1.6/2
=> F = 0.8m
Hence the focal length of concave mirror is 0.8 m
Frequency is inversely proportional to wavelength.
Wavelength is the spacial period, and more generally the frequency is inversely proportional to the period.
If the wave's speed if c, then f=c/l where l is the wavelength.
