Physics Light Part 12 (Spherical Mirror Application) Class 7 VII

TL;DR

Concave and convex mirrors have various applications, such as in shaving mirrors, torches, car headlights, and streetlights.

Transcript

hello friends this video on light part 12 is brought to you by exam feel calm no more pure prom exam so now that we have seen the various types of images which are formed by both concave and convex mirrors so let's see where we can make use of them so think of this one so where have you seen this so this is the shaving mirror so what kind of images...

Key Insights

• 🪩 Shaving mirrors use concave mirrors to provide enlarged images for better shaving.
• 🙂 Torches have concave mirrors inside them to spread the light.
• 🫵 Rear-view mirrors in vehicles use convex mirrors to provide a wider view.
• 🪩 Dentist mirrors use concave mirrors to produce enlarged images for detailed examination.
• 🎠 Headlights of cars and streetlights use concave and convex mirrors, respectively, based on the desired light distribution.
• 🪩 Spherical mirrors cannot be replaced with plane mirrors in these applications, as they serve specific purposes.
• 🙂 Concave mirrors focus and converge light, while convex mirrors diverge and spread light.

Questions & Answers

Q: What kind of images are formed in shaving mirrors and why?

Shaving mirrors use concave mirrors to produce enlarged images because it helps in providing a better view for shaving.

Q: What type of mirror is present inside torches and why?

Torch lights have concave mirrors inside them because concave mirrors act as converging mirrors, helping in spreading the light.

Q: What kind of mirror is used in rear-view mirrors of vehicles and why?

Rear-view mirrors in cars use convex mirrors because they provide a wider view and produce diminished images, which are characteristics of convex mirrors.

Q: Why are concave mirrors used in dentist mirrors?

Dentists use concave mirrors because they produce enlarged images, allowing dentists to examine teeth in more detail.

Summary & Key Takeaways

• Different types of images are formed by concave and convex mirrors, with concave mirrors producing enlarged images and convex mirrors producing diminished images.

• Shaving mirrors use concave mirrors to provide an enlarged image for better shaving.

• Torches have concave mirrors inside them, which act as converging mirrors to spread the light.

• Rear-view mirrors in cars use convex mirrors to provide an image with a wider view.
