Image Formation by Inclined Mirrors

The video tutorial explains the phenomenon of image formation by multiple reflections using inclined mirrors. It describes how images are formed at equal distances behind the mirrors and how symmetry plays a role in their location. The tutorial also introduces a mathematical formula to calculate the number of images formed based on the angle between the mirrors. The concept of images lying on a circle centered at the intersection of mirrors is highlighted, and a specific relation for calculating the number of images is provided.

What is the initial setup for studying image formation by inclined mirrors?

• Two mirrors inclined at an angle theta with an object on the angle bisector

• A single mirror with an object placed at its center

• Two parallel mirrors with an object between them

• A concave mirror with an object at its focal point

How is the first image formed by the first mirror?

• By direct transmission through the mirror

• By reflection, forming an image at the same distance behind the mirror as the object

• By refraction through the mirror

• By absorption and re-emission of light

What role does symmetry play in the formation of images by inclined mirrors?

• It prevents image formation

• It causes images to overlap

• It helps in locating images at equal distances from the intersection point

• It ensures all images are distorted

What is the pattern of image formation when using inclined mirrors?

• Images form a random pattern

• Images and the object lie on a circle

• Images form a square

• Images form a straight line

What is the significance of the circle in the pattern of image formation?

• It shows the images are equidistant from the intersection point

• It suggests the images are overlapping

• It means the images are not visible

• It indicates the images are distorted

What is the formula for calculating the total number of images formed by inclined mirrors?

• n = 180 / theta

• n = 360 / theta - 1

• n = 360 / theta + 1

• n = theta / 180

Under what condition does the formula for total images apply?

• When theta is greater than 180 degrees

• When theta is less than 90 degrees

• When 180 is divisible by theta

• When theta is an odd number

What happens if 180 is not wholly divisible by theta?

• The number of images is zero

• The images form a straight line

• The number of images is infinite

• The calculation of images becomes more complex

What is the relationship between the angle theta and the number of images formed?

• Smaller theta results in more images

• Theta does not affect the number of images

• Theta only affects the size of images

• Larger theta results in more images

What is the result when the angle between mirrors divides 180 degrees?

• Images divide the semicircle into integral parts

• Images form a square

• Images are not formed

• Images form a triangle
