9. A convex lens of focal length 8 cm forms a real image of the same size as th
object. What will the distance between the object and its image be:
1) 32cm
2) 8cm
3)16cm
4)24cm
Answer: 32cm
Explanation:
Since the focal length of the convex lens is 8cm, the distance between the object and its image be 4f which will be:
= 4 × f
= 4 × focal length
= 4 × 8
= 32cm
The distance between the object and its image is 32cm.
x = 0
while x < 4:
print(x)
x += 1
Make it a for loop
Answer: Here you go :)
Explanation:
x = 0
for n in range(4):
print(x)
