Infrared Waves
Yes, carpet can make a room feel warmer because it acts as an insulator, trapping heat and preventing it from escaping through the floor.
A jacket can make us feel hot because it traps heat close to our body, preventing it from escaping and causing us to feel warmer. It also restricts air flow, which can further contribute to the sensation of heat.
Sound waves are detected by the fact that the waves can cause objects to vibrate. The vibrations from the sound waves must be converted into a signal and then amplified and processed. Your ear and a microphone are common detectors of sound.
Apply a force that causes the object to oscillate. Use a motor or vibrating device to generate vibrations in the object. Strike or hit the object to induce vibrations. Apply sound waves to the object at its resonant frequency to make it vibrate.
When one object vibrates, it creates waves in the surrounding medium (such as air or water) which can then transfer energy to the other object, causing it to vibrate sympathetically even if they are not in direct contact. This phenomenon is known as resonance, where the natural frequency of the second object matches the frequency of the waves produced by the first object.

The friction generated by your hands creates heat.
You will feel warmer as you make out.

You may feel warmer at night compared to during the day because your body temperature naturally rises in the evening as part of your circadian rhythm, and your surroundings may also retain more heat at night. Additionally, your metabolism tends to slow down during sleep, which can make you feel warmer.

A convex lens can change the behavior of light waves by refracting them, causing the light to converge and creating a magnified image of an object. This magnification effect can make an object appear larger than its actual size when viewed through the lens.
When it snows, the air temperature is usually close to or just above freezing. The snowflakes melt as they come into contact with surfaces that are warmer than freezing, such as the ground or buildings. This process releases heat, which can make it feel warmer even though the actual air temperature may not have changed significantly.
