To solve the question "To detect obstacles in their path, bats produce," we need to analyze the options provided and understand the concept of sound waves used by bats.
### Step-by-Step Solution:
1. **Understanding the Question**: The question asks what type of waves bats produce to detect obstacles in their path. This relates to how bats navigate and find prey using sound.
2. **Identifying the Options**: The options given are:
- a) Infrasonic waves
...
How do bats avoid obstacles in their way, when in flight?
The step that proved to be the main challenging obstacle in the production of human insulin by genetic engineering is :
A: When a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the shadow of the obstacle. R: Waves diffracted from the edge of the circular obstacle interfere constructively at the centre of the shadow producing a bright spot.
A : When tiny circular obstacle is placed in the path of light from some distance, a bright spot is seen at the centre of the shadow of the obastacle. R : Destructive interference occurs at the centre of the shadow of circular obstacle.
In a singleslit diffraction experiment, when a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the shadow of the obstacle. Explain why ? State two points of difference the interference pattern obtained in Young's double slit experiment and the diffraction pattern due to a single slit.
A 2 g bullet moving with a velocity of 200 m/s is brought to a sudden stoppage by an obstacle. The total heat produced goes to the bullet. If the specific heat of the bullet is 0.03 cal//g^@C , the rise in its temperature will be
The source is at some distance from an obstacle. Distance between obstacle and the point of observation is .b. and wavelength of light is .lambda. . Then the distance of nth Fresnel Zone will be at a distance……….from the point of observation.
Assertion : When a charge particle moves in a circular path. It produces electromagnetic wave. Reason : Charged particle has acceleration.
Explain how do bats locate the obstacles and prey in their way.
The rule of an "obstacle course" specifies that at the n^(th) obstacle a person has to tos a fair 6 sided die n times. If the sum of points in these n tosses is bigger than 2^(n) , the person is said to have crossed the obstacle. Q. The probability that a person crosses the first two obstacles but fails to cross the third obstacle.
