Tidal waves, also known as storm surges, occur during a tropical cyclone due to the combination of strong winds and low atmospheric pressure. The strong winds push the water towards the shore, causing it to pile up and create a higher water level than normal. Additionally, the low atmospheric pressure at the center of the cyclone can cause the sea level to rise even further. These factors combined result in the formation of tidal waves that can cause significant flooding and damage to coastal areas during a tropical cyclone. **

Water waves are primarily transverse waves, meaning that the particles of the medium (water) move perpendicular to the direction of the wave. However, water waves also have a small component of longitudinal motion, where the particles move parallel to the direction of the wave. This combination of transverse and longitudinal motion is what allows water waves to carry energy and propagate through the medium. **

It is generally not recommended to mix sunscreen with day cream as it can dilute the effectiveness of the sunscreen. Sunscreen should be applied as the last step in your skincare routine, after moisturizer. It is best to apply sunscreen separately to ensure proper protection from the sun's harmful rays. **

Sunscreen came first before face cream. Sunscreen was developed in the early 20th century to protect the skin from harmful UV rays, while face cream has been used for centuries for moisturizing and anti-aging purposes. The importance of sunscreen in protecting the skin from sun damage and skin cancer has led to its development before face creams with SPF protection. **

Sunglasses with mirrored lenses can be both an advantage and a disadvantage. On the one hand, the mirrored coating can help to reduce glare and provide better protection from bright sunlight. This can be especially beneficial for activities like skiing, snowboarding, or driving. On the other hand, the mirrored coating can make it difficult for others to see your eyes, which may be a disadvantage in social situations where eye contact is important. Additionally, the mirrored coating may also scratch more easily than non-mirrored lenses. Ultimately, the decision to wear sunglasses with mirrored lenses depends on personal preference and the specific use case. **

No, radio waves, including extremely low frequency (ELF) waves, do not travel faster than the speed of light. The speed of light in a vacuum is approximately 299,792 kilometers per second, and radio waves, including ELF waves, travel at the speed of light. This means that radio waves, including ELF waves, do not exceed the speed of light. **

It is generally recommended to apply sunscreen as the last step in your skincare routine, after all other products. This is because sunscreen needs to form a protective barrier on the skin to effectively block out harmful UV rays. Applying sunscreen last ensures that it is not diluted or disrupted by other products, maximizing its effectiveness. However, if your day cream contains SPF, you can apply it before sunscreen as long as it provides sufficient protection. **

The best sun cream for you depends on your skin type, any specific skin concerns, and your personal preferences. Look for a broad-spectrum sunscreen with SPF 30 or higher, which will protect against both UVA and UVB rays. Additionally, consider a water-resistant formula if you'll be swimming or sweating. It's also important to choose a sunscreen that you'll actually enjoy using, whether that's a lightweight lotion, a hydrating cream, or a convenient spray. Ultimately, the best sun cream is one that you'll apply consistently and that meets your specific needs. **
