Explanation:
(i)
O is the object and I is the image.
The image formed is enlarged and it is erect. So the magnification will be positive (+) and greater than 1.
Refer above image. 1
(ii)
O is the object and I is the image.
The image formed is diminished and erect. So the magnification will be positive (+) and less than1.
Refer above image. 2
(iii)
The image will be formed as the 2F on the other side of the lens and it will be of same of the object.
Volume= Length X width X height.
Plug in the values for each and solve for the volume.
V= (L)(W)(H)
V=(4cm)(5cm)(10cm).
In scientific inquiry, hypothesis acts as the road map that guide the researcher and show him how to go about his scientific investigation. Hypothesis provides a testable explanation for an observation and serves as the starting point for the scientific investigation.
Answer:
Green, blue, indigo and violet.
Explanation:
The velocity of a wave is given by
where
f = Frequency = 
= Wavelength
The wavelength of the wave is 550.459 nm
Green light has wavelength which ranges from 500-565 nm.
So, the light which observed is green light and lower in wavelength than green light i.e., green, blue, indigo and violet.
