Answer:
2.45 x 10^-2
Explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.0245 into scientific notation, follow these steps:
Step 1) Move the decimal 2 times to right in the number so that the resulting number, m = 2.45, is greater than or equal to 1 but less than 10
Step 2) Since we moved the decimal to the right the exponent n is negative
n = -2
Step 3) Write in the scientific notation form m × 10n
= 2.45 × 10-2
Therefore,
2.45 × 10-2 is the scientific notation form of 0.0245 number and 2.45e-2 is the scientific e-notation form for 0.0245

A,B and D are correct statements
Answer:
true b, e
Explanation:
The expression that describes the diffraction of a grating is
d sin θ = m λ
where d is the separation between the slits, m is the order of the spectrum
let's analyze the different answers
a) False. The size (height) of the slits does not influence the resolution, the number of them per unit of length influences, the greater the number, the smaller the distance (d) this they
b) True. The spectrum is resolved on a screen, in the form that each wavelength corresponds to a fixed distance from the central maximum, for a given order
c) False. The exit slit selects a given wavelength, but does not deflect the beam from its path
d) False. The slit lets in light, but does not measure its intensity
e) True. For a continuous spectrum, the wavelength variation that passes through a slit is proportional to its width. For a discrete spectrum the width of the slit does not affect the wavelength
