Yes! Fossils, The outlines of the continents and geological features .
Answer:
.09 mm
Explanation:
In case of diffraction by single slit with width a the width of central maxima is given below
width = 2 λD/a
where λ is wavelength of light , D is distance of screen , a is width o slit
substituting the given values
14 x 10⁻³ = 
a = .09 mm
b) If a is greater , width of central maxima will be less wide.
Answer:
wavelength= 5.35×10cm=0.535m
f= 16000hz
v= wavelength × f= 0.535×16000=8560m/sec
There are no correct choices on the list you provided. Any unit of acceleration is (a unit of length) divided by (a unit of time, squared).
Answer:
A. The object is placed at focal point on the principal axis.
This where no image is formed.
Explanation:
This is because the position of the object is at infinity.So the position of the image will be At the focus where the size of the image will be highly diminished, point-sized.
The nature of the image will be Real and Inverted.
Due to these reasons no image if formed when object is placed on the principal axis.
