A.    Answer the following questions in Short . 

Q.1    What is Augmented Reality ? What is the main purpose of Augmented Reality in enhancing user Experiences ? 

Ans:-     Augmented reality (AR) overlays interactive digital images and information onto the real world, enhancing perception. Using smartphones or headsets, users can view virtual objects, like furniture, seamlessly integrated into physical surroundings in real time.

Q.2    Explain how virtual Reality works . What kind of equipment do you need to use it ? 

Ans:-    Virtual Reality works by creating a computer-generated 3D environment viewed through a VR headset. Sensors track head and hand movements, updating visuals instantly. Required equipment includes a VR headset, motion controllers, tracking sensors, and sometimes a powerful computer or gaming console.

Q.3    Different between AR and VR . 

Ans:-    Augmented Reality (AR): - Augmented Reality is a technology that overlays digital images, information, or objects onto the real-world environment, enhancing what users see and interact with without replacing the physical surroundings.

Virtual Reality (VR):- Virtual Reality is a technology that creates a fully computer-generated environment that completely replaces the real world, allowing users to experience and interact within a simulated digital space.

Q.4    Explain any three types of Augmented Reality  . 

Ans:-    Augmented Reality Type :

1. Marker-Based AR: Uses printed markers or images to trigger and display digital content.

2. Markerless AR: Uses GPS and sensors to place virtual objects without physical markers.

3. Projection-Based AR: Projects digital images onto real surfaces and allows interaction.

 Q.5    List three uses each of Augmented Reality and Virtual Reality . 

Ans:-   Uses of Augmented Reality (AR):- 

1. Virtual furniture placement in rooms before purchase.

A.Answer the following questions. 

Q.1    What do you understand by Iterative statement ? 

Ans:-    Iterative statements in Python allow for repetitive execution of code until a specified condition is met . 

Q.2    Explain about "for loop" and  "while loop" in Python. 

Ans:- For Loop :- A for loop iterates through sequences like lists, strings, or ranges, executing code for each element automatically. It’s ideal when iteration count is predetermined or finite.

While Loop :- A while loop repeatedly executes code as long as its condition remains true. It requires manual updates to avoid infinite repetition, making it useful when iteration depends on dynamic conditions.

Q.3    Define List and Tuple.

Ans:-   List:- A list is an ordered collection of items that can be modified . Lists are represented using square brackets. 

Example:- Fruits= [ "Apple" , "Mango", "Banana" , "Grapes" ]

Tuple:- A tuple is an ordered collection of items that cannot be changed after creation . Tuple are written using round brackets . 

Example :- names= ("Apple" , "Mango", "Banana" , "Grapes")

Q.4   Describe the role of the range() function in python loops . How does it control the number of iterations in a for loop ? 

Ans:-    The range() function is commonly used in a for loop to execute a block of code a specific number of times. It generates a sequence of numbers starting from 0 by default, incrementing by 1 unless specified otherwise, and stopping just before the given endpoint.

Q.5   What is the purpose of the else block in a for loop , and under what conditions will it executed? 

Ans:-     In Python, the else keyword can be used with a for loop, but it works differently from how it is used in if statements. In a for loop, the else block is executed only if the loop completes normally, without encountering a break statement.

Q.6    What are infinite loops ? How can an infinite loop be useful in real world programming scenarios ?

Ans:-     An infinite loop occurs when a loop keeps running endlessly because the condition to stop the loop is never met. This can be useful in situations where you need a program to keep running, such as in a game, or monitoring systems, until a specific action occurs.
