אשכול דמיון בעדשות חלק ג - זכוכית מגדלת

1.2 מדרגה 2 לבעיית מטרה 1

בעיה 1.2.1

הנר $(AB)$ מאונך לציר העדשה $(HF_1)$ .

דמות הנר $(HG)$ מאונכת לציר העדשה.

קרן האור $(BD)$ מקבילה לציר העדשה.

אורך הנר 4 ס"מ,

אורך דמות הנר 10 ס"מ,

מרחק הנר ממרכז העדשה הוא 2 ס"מ.

חשבו את $HA$ .

תוכלו להיעזר ביישומון המצורף.

אחרי שפתרתם את השאלות במדרגה 2, חזרו לבעיית מטרה 1.

יישומון

ניתן לשנות את מיקום הנר, על-ידי גרירת נקודה A ימינה ושמאלה.
ניתן לשנות את גובה הנר, על-ידי גרירת נקודה B למעלה ולמטה.
ניתן לסמן משולשים שונים, על-ידי בחירת צבע המשולש בתפריט, ובחירת 3 קודקודים.
