Calculation for question 3:

Answer to Question 4, the Cassegrainian telescope:

Project 1 - Field of View

a. Calculation of Magnification 35 mm eyepiece:

Magnification = _________________________________________________________

25 mm eyepiece:

Magnification = _________________________________________________________

10 mm eyepiece: Magnification = _________________________________________________________

b. Calculation of Field of View

Number

of bricks

Number

of grout lines

Calculated length of wall segment

(in meters!)

For 35mm

eyepiece

For

25mm eyepiece

For

10mm eyepiece

Using the ‘small angle formula’, the Field of View is calculated as (show calculation):

35mm eyepiece: FoV =

25mm eyepiece: FoV =

10mm eyepiece: FoV =

Project 2 Distance to Object

Number

of bricks

Number

of grout lines

Calculated length of wall segment

(in meters!)

For 35mm eyepiece

For

25mm eyepiece

For 10mm

eyepiece

Calculated distance using 10 mm eyepiece:

Calculated distance using 25 mm eyepiece

Calculated distance using 35 mm eyepiece
