The flashlight's beam will all be refracted towards a central axis. But, this is still dependent on the type of lens that is used for the said activity. The speed of light will vary depending whether the lens is a concave or a convex lens. The exit point of the light will always head towards the central axis.

Answer:

They will all be refracted toward a central axis

Explanation:

They are going to bend the light in toward a central axis because they will either magnify, or deacrease the sizes. On a concave there will eventually be a focal point and the image will flip.

The time between a lightning flash and the following thunderclap may be used to estimate, in kilometers, how far away a storm is
Kruka [31]

Given Information:  

Elapsed time = t = 6 seconds

Required Information:

Distance = d = ?

Answer:

Distance = d = 2.058 km

Explanation:

We know that the speed of sound in the air is given by

v = 343 m/s

The relation between distance, speed and time is given by

distance = speed*time

substituting the given values yields,

distance = 343*6

distance = 2058 m

There are 1000 meters in 1 km so

d = 2058/1000

d = 2.058 km

Therefore, the storm is about 2.058 km away when elapse time between the lightning and the thunderclap is 6 seconds.

What would you do if you are caught on thunder storm
Norma-Jean [14]

If caught outside in a thunderstorm, find a low spot away from trees, fences, and poles. If your skin tingles and hair stands on end, lightning is about to strike. Crouch down immediately, balancing on the balls of your feet, placing hands on knees with head between them.
