What does ef mean on tornado scale?

EF on the tornado scale stands for Enhanced Fujita scale. It is used to classify tornado intensity based on the damage caused by the tornado, ranging from EF0 (weakest) to EF5 (strongest). The EF scale takes into account the strength of the wind and the type of damage observed.


May a F-3 tornado blow up a house?

An EF-3 tornado can cause significant damage to a house, including tearing off roof materials and exterior walls. However, the complete destruction of a house would typically require a higher intensity tornado, such as an EF-4 or EF-5.


How long does an EF-5 tornado last?

There is no given duration for a tornado of any intensity, but a tornado as violent as an EF5 will generally last fairly long. Most will likely last for at least 20 minutes. Some may last for well over an hour.


What category is a 250mph tornado?

There is no "category" for winds in a tornado. Tornadoes are measured by the Enhanced Fujita Scale, which simply is a rating based on the amount of damage done. It ranges from weakest EF-0, to strongest EF-5....250mph winds are "capable" of producing EF-5 damage, should it move over certain sturdy structures. However, a tornado over an open field with 250mph will not get an EF-5 rating because it has no sturdy structures for it to damage. Tornadoes are rated after the fact based on the amount of damage done. So while a 250mph wind "could" produce EF-5 damage, it's got to move over the right structures for that damage to be realized and the tornado given that rating.


What is the most common tornado in EF ratings?

The most common rating for a tornado is EF0, accounting for almost 60% of tornadoes in the U.S. The higher the rating, the less often it occurs.

What are the best EF-M lenses that are compatible with the EF mount?

The best EF-M lenses compatible with the EF mount are the Canon EF-M 22mm f/2 STM, Canon EF-M 32mm f/1.4 STM, and Canon EF-M 11-22mm f/4-5.6 IS STM.


What are the differences between the Canon EF and EF-S lenses?

The main difference between Canon EF and EF-S lenses is their compatibility with different camera bodies. EF lenses are compatible with both full-frame and APS-C sensor cameras, while EF-S lenses are specifically designed for APS-C sensor cameras. EF-S lenses are generally smaller and lighter than EF lenses, but EF lenses offer a wider range of focal lengths.

What are the main differences between EF and EF-M lenses for Canon cameras?

EF lenses are designed for Canon DSLR cameras and have a larger mount diameter, while EF-M lenses are designed for Canon mirrorless cameras and have a smaller mount diameter. This means that EF lenses are not compatible with EF-M cameras, and vice versa. Additionally, EF-M lenses are typically more compact and lightweight compared to EF lenses.


Are EF and EF-S lenses compatible with each other?

No, EF and EF-S lenses are not compatible with each other due to differences in their mount sizes and designs. EF lenses are designed for full-frame cameras, while EF-S lenses are specifically made for APS-C sensor cameras.


What are the differences between EF, EF-S, and EF-M lenses in terms of compatibility and functionality with Canon cameras?

EF lenses are compatible with all Canon cameras, while EF-S lenses are designed specifically for Canon APS-C sensor cameras. EF-M lenses are designed for Canon mirrorless cameras. EF lenses offer the most versatility in terms of compatibility, while EF-S and EF-M lenses are more limited in their compatibility but are optimized for specific camera types.
